MULTI-TIER PRICING OF INDIVIDUAL PRODUCTS BASED ON VOLUME
DISCOUNTS
Abstract
A point of sale system or other computer system stores a product
pricing database in which a full price and discount prices
corresponding to one or more discount pricing tiers are stored for
each product available for sale. Each of the discount prices for a
given product has an associated threshold purchase total that has
to be satisfied before the discount price is applied to a
transaction. When a transaction occurs, the purchase total for the
transaction is first calculated on the basis of full retail prices
for the products and the purchase total for the transaction is
compared with one or more threshold purchase totals which
correspond to the discount pricing tiers. If a discount pricing
tier is applicable (e.g. the calculated purchase total for the
transaction is at least equal to a threshold purchase total), the
appropriate discount prices for each product in the transaction are
retrieved and used to calculate a reduced purchase total for the
transaction. Qualification for discount pricing can also be based
on, for example, a customer's purchasing history, or the number of
a certain type of product included in the transaction instead of
the purchase total of a transaction.

SYSTEM AND METHOD FOR THE MANAGEMENT OF GROUP REWARDS", filed on

FIELD OF THE INVENTION
[0004] The method and apparatus of the present invention relate to
calculating discounted prices for products sold at retail.
BACKGROUND
[0005] It is a common practice for retail sellers to discount the
prices of products in order to attract customers and increase sales
volume. One very widespread method of discounting involves issuance
of coupons. One type of coupon may be presented by the buyer when a
particular product is purchased, in order to obtain a reduced price
for the product. Another type of coupon may be presented to obtain
X dollars off or X percent off a total purchase of Y dollars.
[0006] It is also common to extend discounts of the latter kind
without issuing or requiring presentation of a coupon. For example,
retailers frequently advertise special sales of X percent off all
purchases made on a given day or all purchases made on that day of
over a given amount.
[0007] Another well-known promotional approach invites the customer
to "buy one, and get one free". Alternatively and as an inducement
to purchase larger quantities of products, discount prices are
offered for the purchase of increased quantities of products
(commonly referred to as "bulk discounts"), as in "one for 50 ,
three for $1".
[0008] Other discount plans are available only to customers who are
"members" of the plan. These include membership club "superstores"
that offer discounted prices on all products sold but are not open
to the general public. Other stores (particularly supermarkets) are
open to all but issue preferred customer cards that entitle the
holder to discounts on some or all products in the store.
[0009] Most, if not all, of these discounting approaches have some
disadvantages. For example, coupons or other promotions which apply
only to a certain product or products will do little to attract
customers who are not interested in purchasing those products. On
the other hand, across-the-board discount offers may be
disadvantageous to the retailer, since some customers may
concentrate their purchases on products which carry a low profit
margin. When this occurs, the retailer may find that additional
revenues generated by the promotion do not translate into much, if
any, additional profit. One way in which retailers have attempted
to deal with this problem is by excluding low-margin products from
sales of the "take 10% off everything" type.
[0010] In a somewhat similar known approach, it is known in the
supermarket environment to grant a discount of 10% off a group of
products if the total purchase amount spent by a customer on a
visit to the store is at least $20. If the total purchase amount is
at least $50, then a 20% discount is applied to products purchased
from the qualified group of products.
[0011] None of the known discounting and promotional techniques has
fully addressed the need to balance the attractive features of
discounting with preservation of profit margins on the products to
be sold.
SUMMARY OF THE INVENTION
[0012] In a preferred embodiment, the present invention provides a
method and apparatus for calculating a purchase total for a
transaction, in which: (a) a number of product identifiers are
received, each representing a respective product to be purchased,
(b) an initial purchase total for the transaction is calculated on
the basis of a respective first price for each of the products to
be purchased, (c) it is determined whether the initial purchase
total is at least equal to a predetermined threshold purchase
total, and (d) if such is the case, a reduced purchase total is
calculated for the transaction on the basis of respective second
prices for each of the products to be purchased, where at least
some of the second prices are lower than the corresponding first
prices. The first and second prices (and perhaps third and fourth
or even more prices) are, in one embodiment, stored in a database
and are retrieved as necessary to calculate the initial purchase
total and a discounted purchase total for which the transaction is
qualified.
[0013] It is contemplated to apply the present invention in a
variety of different types of retail stores, including
supermarkets, drugstores and quick service restaurants. In such
applications, a conventional point of sale system is programmed to
carry out the invention. A suitable pricing database, including
multiple prices for at least some of the products available for
sale, is stored in the point of sale system.
[0014] It is also contemplated to apply the present invention to
other retailing outlets including catalog-ordering facilities, and
shopping Web sites maintained on the Internet.
[0015] The customer may be permitted to qualify for discounted
prices on the products available for sale on the basis of a number
of criteria, including a purchase total of a current purchase
transaction, the sum of purchase totals over a predetermined period
of time, membership in a group that has maintained or reached a
predetermined sum of purchase totals or other level of purchases,
purchasing of a predetermined combination of products, or
purchasing a predetermined number of qualifying products, such as a
number of products which carry the same brand.
[0016] The discounting methods and apparatus of the present
invention permit the seller to predetermine and store one or more
levels of discount prices on a product-by-product basis. The seller
may therefore be able to carefully balance the reduction in profit
margin for each product with the overall level of spending made by
the customer. For example, the discount prices of a given product
may have a predefined relationship with the retail price of the
product. For example, the discount price may be set such that the
difference between the retail price and the discount price for a
high margin product is substantially greater than the difference
between the retail price and the discount price of a low margin
product. As a result, the benefit received by the retailer in
generating additional sales volume can be set to outweigh the
reduction in profit margins resulting from the discounts.

[0069] An embodiment of the invention will now be described with
reference to FIGS. 1-3, 4A and 5-8.
[0070] Referring initially to FIG. 1, reference numeral 50
generally indicates a point of sale system in which a first
embodiment of the invention is applied. It is preferred that the
hardware making up the point of sale system 50 be of conventional
design. The present embodiment will be described in the context of
a retail outlet such as a supermarket, and the point of sale system
may, for example, be constituted in terms of its hardware by
point-of-sale terminal equipment and an associated data network of
the type typically employed in a supermarket. As somewhat
schematically illustrated in FIG. 1, the point of sale system 50 is
shown as including point of sale (POS) terminals 52 and a central
server unit 54 connected by data paths 56 to the POS terminals 52.
Although only three POS terminals 52 are shown in FIG. 1, it will
be recognized that in many cases a greater number of such terminals
52 will be installed in a retail store and connected to the central
server 54. Of course, it is also contemplated to apply the
invention in a point of sale system having fewer than three
terminals.
[0071] FIG. 2 is a block diagram which shows some details of a
typical one of the POS terminals 52.
[0072] The POS terminal 52 includes a processor 58 which controls
operation of the POS terminal 52. The processor 58 may be one or
more conventional microprocessors or micro-controllers. Other
conventional components of the POS terminal 52, all of which are
connected to the processor 58, include a printer 60 for printing,
for example, sales receipts and credit card slips, one or more data
input devices 62, such as, for example, a keyboard and a bar code
reader, and a character and/or CRT display 64 which provides an
indication, such as a visual indication, of product or other data
inputted into, or being processed by, the POS terminal 52. Also
connected to the processor 58 is a communications interface
component 66 through which the processor 58 exchanges data with the
central server 54.
[0073] Another component of the POS terminal 52 shown in FIG. 2 is
a data memory device 68 which is accessible by the processor 58. A
program 70 is stored in the data memory device 68. The program 70
controls the processor 58 to carry out functions of the present
invention which will be described below.
[0074] Referring now to FIG. 3, some details of the central server
54 of FIG. 1 will now be described.
[0075] The central server 54 includes, and is controlled by, a
processor 72. Processor 72 may comprise as one or more processors,
such as one or more Pentium.RTM. microprocessors. If the processor
comprises a plurality of microprocessors, the plurality of
microprocessors may or may not operate in parallel. Connected to
the processor 72 are conventional components such as an input
device 74, a display device 76, a printer 78 and a communication
interface 80. As is customary, the central server 54 is preferably
realized using suitable personal computer, computer workstation or
mini-computer hardware. The peripheral devices 74, 76 and 78 may
comprise, for example, a keyboard/mouse, a computer monitor and a
computer output printer, respectively. The communication interface
80 allows the processor 72 to exchange data with the POS terminals
52 via the data links 56 (FIGS. 1 and 2).
[0076] Continuing to refer to FIG. 3, the central server 54 also
includes a data memory device 82, which is accessible by the
processor 72 and preferably is a mass storage device such as a hard
disk drive. The processor 72 is in communication with the data
memory device 82. The data memory device 82 comprises an
appropriate combination of magnetic, optical and/or semiconductor
memory, and may include Random Access Memory (RAM), Read-Only
Memory (ROM) and/or a hard disk. The processor 72 and the memory
device 82 may each be (i) located entirely within a single computer
or other computing device; (ii) connected to each other by a remote
communication medium, such as a serial port cable, telephone line
or radio frequency transceiver; or (iii) a combination thereof. In
one embodiment, the central server 54 may comprise one or more
computers that are connected to a remote server computer for
maintaining databases.
[0077] The data memory device 82 stores a program 84 for
controlling the processor 72. The processor 72 performs
instructions of the program 84, and thereby operates in accordance
with the present invention, and particularly in accordance with the
methods described in detail herein. The program 84 may be stored in
a compressed, uncompiled and/or encrypted format. The program 84
furthermore includes program elements that may be necessary, such
as an operating system, a database management system and "device
drivers" for allowing the processor 72 to interface with computer
peripheral devices. Appropriate device drivers and other necessary
program elements are known to those skilled in the art, and need
not be described in detail herein.
[0078] The storage device 82 also stores (i) a price database 86,
(ii) a condition database 88, (iii) a transaction database 90, (iv)
a customer database 92, and (v) a team database 94. The databases
86, 88, 90, 92, and 94 are described in detail below and depicted
with exemplary entries in the accompanying figures. As will be
understood by those skilled in the art, the schematic illustrations
and accompanying descriptions of the databases presented herein are
exemplary arrangements for stored representations of
information.
[0079] A number of other arrangements may be employed besides those
suggested by the databases shown. Similarly, the illustrated
entries of the databases represent exemplary information, and those
skilled in the art will understand that the number and content of
the entries can be different from those illustrated herein.
[0080] The price database 86 includes pricing information for
products to be sold in the store. The condition database 88
indicates conditions that have to be met to qualify for discount
pricing tiers. The transaction database 90 stores information
concerning purchase transactions carried out at the POS terminals.
The customer database 92 stores information such as purchasing
histories for customers of the store. The team database 94 stores
data indicating "purchasing teams" (e.g. several customers
associated together via the record in the customer database) with
which store customers may be affiliated.
[0081] FIG. 4A is a table 4000 which depicts a prior art database
in which the data is organized according to a prior art data
structure. The data structure includes a product identifier data
object 4001 and a price data object 4002 for the product identifier
data object. The product identifier uniquely identifies a product
and the price indicates the price to pay for that product.
[0082] FIG. 4B depicts the prior art table 4000 of FIG. 4A storing
illustrative data. Each of records 4010, 4020 and 4030 specifies a
product and its price. Typically, in a conventional retail system,
the POS terminal retrieves the price associated with a product,
based on a product identifier, from table such as table 4000 and
applies the retrieved price for the product to the current
transaction.
[0083] FIG. 5A depicts a database in which the data is organized
according to a data structure in accordance with the present
invention. In one embodiment, such data is stored on a computer
readable medium and is accessible by a program executed on a data
processing system, also described herein.
[0084] The data structure includes a product identifier data object
5052 and a plurality of price data objects 5054, 5056, 5058 and
5060 for the product identifier data object 5052. The product
identifier uniquely identifies a product and each price indicates
the price to pay for that product under a particular condition. A
condition table 5000 includes a respective condition data object
5002, 5004, 5006, and 5008 for each price data object 5054, 5056,
5058, and 5060. For example, condition data object 5002 corresponds
to price data object 5054. When a condition is satisfied, the
satisfied condition indicates one price which is to be paid for the
product.
[0085] FIG. 5B depicts the database of FIG. 5A storing illustrative
data. The product "P135" identified by reference numeral 5052 has
four associated prices "$2.99" (5054), "$2.95" (5056), "$2.90"
(5058) and "$2.75" (5060). The condition table 5000 includes
condition data objects, 5002, 5004, 5006 and 5008 for the price
data objects 5052, 5054, 5056 and 5058 respectively. The
illustrative condition data objects 5002, 5004, 5006 and 5008
define conditions in terms of a value, and in particular in terms
of ranges of the value. The value may be, for example, the purchase
total of a single transaction, the purchase total of a plurality of
transactions, or the average purchase total of a plurality of
transactions. For illustrative purposes, FIG. 5B illustrates the
conditions in terms of a purchase total (PT) value range. For
example, FIG. 5B illustrates that the price of "$2.99" (5054) for
product "P135" (5052) has an associated purchase total value range
of $0 through $100. Thus, if a purchase total of a transaction is a
value greater than $0 and less than $75, the price applied to the
transaction for the product "P135" included in such a transaction
is $2.99. If however, the purchase total of a transaction is a
value greater than $75 and not greater than $100, then the price
for the product "P135" as applied to such a transaction is $2.95,
as indicated by the condition value range 5004 and the
corresponding price data object 5056.
[0086] The condition data objects may define mutually exclusive
conditions. For example, if the condition data objects define
conditions in terms of ranges of a value, the ranges may be
mutually exclusive (i.e. non-overlapping). Similarly, the condition
data objects may define exhaustive conditions such that under any
conditions at least one condition is always satisfied. Thus, if the
condition data objects define both mutually exclusive conditions
and exhaustive conditions, then under any conditions exactly one
condition is satisfied.
[0087] FIG. 6A is a condition table 6000, which illustrates an
embodiment of the condition database 88 of the central controller
of FIG. 3, in accordance with another embodiment of the present
invention. The condition table 6000 includes a plurality of records
6001, 6002, and 6003, each record specifying a pricing tier name
6005 and a condition 6010 that corresponds to that pricing tier
name. The condition table 6000 defines conditions in terms of a
value, and in particular in terms of ranges of the value.
[0088] Each range is defined by a value and the value(s) of other
record(s). In FIG. 6A, this value is the purchase total threshold.
For example, the record 6001 specifies a pricing tier named "GOLD"
and a value "$150". The record 6002 specifies a pricing tier named
"SILVER" and a value "$100". The record 6001 thus defines a range
"greater than $150", and the record 6002 defines a range "between
$100 and $150".
[0089] FIG. 6B is a condition table 6020, which illustrates an
embodiment of the condition database 88 of the central controller
of FIG. 3, in accordance with another embodiment of the present
invention. The condition table 6020 is similar to the condition
table 6000 of FIG. 6A, and likewise includes a plurality of records
6021, 6022, 6023, and 6024, each record specifying a pricing tier
name 6025 and a condition 6030. However, the condition table 6020
defines conditions in terms of explicit ranges of a value within
each record 6021, 6022, 6023, and 6024. For example, record 6022
defines the purchase total (PT) range for the "Silver" pricing tier
as a value not less than $100 and less than $150.
[0090] FIG. 6C is a condition table 6050, illustrative of the
condition database 88 of the central controller 54 (FIG. 3), in
accordance with another embodiment of the present invention. The
condition table 6050 is similar to the condition table 6000 of FIG.
6A, and likewise includes a plurality of records 6051, 6052, 6053,
and 6054, each record specifying a pricing tier name 6055 and a
condition 6060 that corresponds to each respective pricing tier
name. However, in FIG. 6C the condition table 6050 defines
conditions in terms of a number of "qualifying" products that are
purchased, rather than in terms of a purchase total.
[0091] FIG. 7 is a portion 7000 of the database of FIG. 5B for ease
of illustration. The illustrative portion 7000 is of the type that
may be presented to a customer on a shelf label to inform the
customer of the possible prices for a product. In a preferred
embodiment of the invention, prices corresponding to three discount
tiers, in addition to the retail price, are assigned to many or all
of the products sold in the store, and shelf labels in the format
shown in the illustrative portion 7000 are displayed on store
shelves adjacent to all of the products to which the discount
prices have been assigned. FIG. 7 also depicts an illustrative
display 7050 that indicates the various conditions of the condition
table 6A. The illustrative display 7050 is of the type that may be
presented to a customer to inform the customer of the conditions,
which in the present example are based on the purchase total. It is
contemplated that, in one embodiment of the present invention, the
illustrative display 7050 and/or the illustrative portion 7000 may
be in digital format and the pricing tier threshold purchase totals
and corresponding product prices are changed dynamically based on
current sales volume or other conditions.
[0092] FIG. 8 is a table 8000 which is illustrative of one
embodiment of the price database 86 of the central controller 54
(FIG. 3). The table 8000 is similar to the portion 7000 of FIG. 7,
yet specifies a plurality of products. In an embodiment such as
illustrated in FIG. 8, each condition corresponds to a respective
subset of the prices. Each respective subset of prices includes one
respective price for each of the product identifiers. In addition,
for any product, each price corresponds to one respective
condition. For example, the condition "GOLD PRICE" corresponds to a
subset of prices that includes the first price of each of the
product identifiers. The product identified by "P101" has four
prices, each corresponding to one of the respective conditions
"GOLD PRICE", "SILVER PRICE", "BRONZE PRICE" and "RETAIL
PRICE".
[0093] Table 8000 includes a number of records 8001, 8002, 8003,
8004, 8005 each of which has six attributes, corresponding to the
six columns shown table 8000. The six columns respectively are
indicated in table 8000 as denoting the "product identifier"
(reference numeral 8010), which may be an alphanumeric string of
digits that uniquely identify the product in question; the product
description (reference numeral 8020); prices corresponding to a
"gold" discount pricing tier (reference numeral 8030), which, in
the illustrated embodiment, are the most favorable prices from the
customer's point of view; prices corresponding to a "silver"
pricing tier (reference numeral 8040), which, in the illustrated
embodiment, is a tier that is less favorable than the gold tier;
prices corresponding to a "bronze" discount pricing tier (reference
numeral 8050), which, in the illustrated embodiment, is a tier of
prices that is less favorable than the silver tier, and the retail
pricing tier (reference numeral 8060) which represent the prices at
which products are sold when no discount is applicable. In the
examples provided in table 8000, the bronze price for each product
is lower than the retail price, the silver price for each product
is lower than the bronze price, and the gold price for each product
is lower than the silver price; except that for one product,
"P105", granola cereal, the pricing in all four tiers is the same.
Of course it is understood that any number and hierarchical order
of pricing tiers could be used in accordance with the present
invention.
[0094] The example of FIG. 8 illustrates the great flexibility in
varying the pricing from tier to tier and varying the discount
structure from product to product that is a key advantage of the
present invention. For example, if the information for one of the
products other than "granola cereal" is examined, it will be noted
that the decrease in price from one tier to the other is variable.
For instance, in the case of product "P101", "cream cheese", the
reduction in price in the bronze tier relative to the retail
pricing tier is 5 , whereas the decrease in the silver discount
pricing tier as compared to the bronze discount pricing tier is 10
, and the reduction in price from the silver discount pricing tier
to the gold discount pricing tier is 15 .
[0095] It will also be observed that looking across all of the
products, the changes in price from one tier to another tier need
not be uniform across the different products. For example, the
reduction in price from the silver discount pricing tier to the
gold discount pricing tier for cream cheese is just under 10%, the
reduction in price for orange juice between the two discount
pricing tiers is just under 5%, but the reduction in price for rye
bread is in excess of 20%.
[0096] FIG. 9A illustrates a database in which the data is
organized according to a data structure in accordance with another
embodiment of the present invention. The data structure includes a
product identifier data object 9002 and a plurality of price data
objects 9004, 9006, and 9008 for the product identifier data
object. The product identifier uniquely identifies a product and
each price indicates the price to pay for that product under a
particular condition. The product identifier data object is also
associated with its own condition table 9010, which includes a
respective condition data object 9012, 9014, and 9016 for each
price data object. When a condition is satisfied, the satisfied
condition indicates one price which is to be paid for the
product.
[0097] In contrast to the embodiment presented in FIG. 5A, in the
embodiment depicted in FIG. 9A each product is associated with its
own condition table. Accordingly, different products may have
different conditions under which various prices are applicable, and
different products may have different numbers of prices. In fact,
the conditions of different products may be defined in different
terms. For example, a first product may have prices based on the
purchase total, while a second product has prices based on a number
of qualifying products that are purchased.
[0098] FIG. 9B illustrates the database of FIG. 9A storing
illustrative data. The product identified by reference numeral 9002
has four associated prices $2.99 (9004), $2.95 (9006), and $2.90
(9008). The condition table 9010 for the product includes condition
data objects 9012, 9014, and 9016 for the price data objects 9004,
9006, and 9008 respectively. The illustrative condition data
objects 9012, 9014, and 9016 define conditions in terms of a value,
and in particular in terms of ranges of a purchase total. For
example, the condition data object 9014 defines the condition of a
purchase total (PT) range of $75 to $100. Thus, if the condition of
condition data object 9014 is met, the price indicated by
corresponding price data object 9006 is applied for product "P135."
That is, if a purchase total of a transaction is greater than $75
but not greater than $100, the price applied to the transaction for
product "P135" is $2.95.
[0099] FIG. 9C is table 1000 and similarly depicts the database of
FIG. 9A storing illustrative data for three products. The product
identified by reference numeral 1010 has two associated prices 1012
and 1014. The condition table 1015 for the product 1010 includes
condition data objects 1016 and 1018 for the price data objects
1012 and 1014 respectively. The illustrative condition data objects
1016 and 1018 define conditions in terms of ranges of a purchase
total.
[0100] The product identified by reference numeral 1020 also has
two associated prices 1022 and 1024. The condition table 1025 for
the product 1020 includes condition data objects 1026 and 1028 for
the price data objects 1022 and 1024 respectively. The illustrative
condition data objects 1026 and 1028 also define conditions in
terms of ranges of a purchase total.
[0101] The product identified by reference numeral 1030 has three
associated prices 1032, 1034 and 1036. The condition table 1037 for
the product 1030 includes condition data objects 1038, 1039 and
1040 for the price data objects 1032, 1034 and 1036 respectively.
The illustrative condition data objects 1038, 1039 and 1040 also
define conditions in terms of ranges of a purchase total.
[0102] FIG. 10A depicts a database in which the data is organized
according to a data structure in accordance with another embodiment
of the present invention. The data structure includes a product
identifier data object 1050 and data objects 1052, 1054 and 1056
that indirectly define price data objects for the product
identifier data object. In particular, in the illustrated
embodiment the data objects 1052, 1054 and 1056 indicate a retail
price, a price decrement and a minimum price respectively. The data
objects 1052, 1054 and 1056 thus define a set of prices ranging
from the retail price to the minimum price, each such price
separated by the magnitude of the price decrement.
[0103] The data structure also includes a condition table 1060
which includes data objects 1062 and 1064. The data objects 1062
and 1064, which indicate a purchase total threshold and a purchase
total increment respectively, define ranges of the purchase total.
The ranges start with the range of purchase totals less than the
purchase total threshold, and each subsequent range spans the
purchase total increment, except for the final range which spans
the values not encompassed by the other ranges.
[0104] FIG. 10B illustrates the database of FIG. 10A storing
illustrative data. The data structure includes product identifier
data object 1050 and data objects 1052, 1054 and 1056 that indicate
a retail price of $2.99, a price decrement of $0.05 and a minimum
price of $2.69 respectively. The data objects 1052, 1054 and 1056
thus define a set of prices ranging from the $2.99 to $2.69, each
such price separated by $0.05.
[0105] The data structure also includes a condition table 1060
which includes data objects 1062 and 1064. The data objects 1062
and 1064 indicate a purchase total threshold of $50.00 and a
purchase total increment of $10.00 respectively. The ranges thus
defined start with the range of purchase totals less than $50.00,
and each subsequent range spans $10.00, except for the final range
which spans the values not encompassed by the other ranges.
[0106] FIG. 10C illustrates a database that is substantially
equivalent to the database depicted in FIG. 10B. In particular, in
the database of FIG. 10C the data is arranged according to the data
structure introduced in FIG. 5. The product identified by reference
numeral 1070 has seven associated prices. The condition table 1080
likewise has seven conditions, one for each of the seven prices.
The prices range from $2.99 to $2.69, each such price separated by
$0.05. The conditions define ranges of purchase total, starting
with the range of purchase totals less than $50.00. Each subsequent
range spans $10.00 (e.g. between $50 and $60), except for the final
range which spans the values not encompassed by the other ranges
(i.e. purchase totals greater than $110). The data structure of
FIG. 10B thus effectively "compresses" the data of FIG. 10C.
Accordingly, the data structure of FIG. 10B can be more efficient
in certain embodiments.
[0107] FIG. 11A illustrates a database in which the data is
organized according to a data structure in accordance with another
embodiment of the present invention. The data structure includes a
product identifier data object 1208 and a data object 1210 that
indirectly defines price data objects for the product identifier
data object.
[0108] The data structure also includes a condition table 1200
which includes data objects 1202, 1204 and 1206. The data objects
1202, 1204 and 1206 each define a function to operate on the data
object 1210 of the product data object 1208. Each of the data
objects 1202, 1204 and 1206 thus cooperates with the data object
1210 to define one price for the product. The functions defined by
the data objects 1202, 1204 and 1206 may be any function of one or
more variables. Similarly, the data object 1210 store values for
the one or more variables.
[0109] FIG. 11B illustrates the database of FIG. 11A storing
illustrative data. The data structure includes a product identifier
data object 1208 and a data object 1210 that defines a retail price
of $15.00. This retail price will indirectly define price data
objects for the product identifier data object 1208. The condition
table 1200 includes data objects 1202, 1204 and 1206, which define
the functions "100% of Retail Price", "90% of Retail Price" and
"80% of Retail Price" respectively. Each of the data objects 1202,
1204 and 1206 thus cooperates with the retail price to define one
price for the product. Specifically, the data objects 1202, 1204
and 1206 and the retail price define the prices $15.00, $13.50, and
$12.00, respectively.
[0110] The following flowcharts are described as being carried out
by either a POS terminal or the central server 54. It is understood
that where the process is described as being performed by a POS
terminal it could alternately be performed by the central server 54
and, similarly, where a process is described as being performed by
the central server it may alternately be performed by a POS
terminal. Also, each of the following processes could be performed
by a combination of the central server 54 and one or more POS
terminals. For example, some of the data could be received by a POS
terminal and transmitted to the central server 54 or the POS
terminal could transmit a request to the central server based on
the received data; the central server 54 could perform an analysis
on any transmitted data, retrieve more data from a database based
on the transmitted data or request; the central server 54 can then
transmit the results of the analysis or the additional data back to
the POS terminal from which the original data or request had been
received; and the POS terminal could apply the result or data to
the current transaction. For example, the product identifiers of
the products included in a transaction may be received by a POS
terminal and transmitted to the central server 54. The central
server 54 could then (i) calculate an initial purchase total, (ii)
determine which pricing tier is applicable, (iii) calculate a final
purchase total based on the applicable pricing tier, and (iv)
transmit the final purchase total (perhaps along with an indication
of the pricing tier that was used to calculate it) to the POS
terminal from which the product identifiers had been received. The
POS terminal could then apply the final purchase total to the
transaction.
[0111] FIG. 12 is a flowchart which illustrates a process carried
out by the POS terminal 52 (FIG. 2) under control of the program 70
for the purpose of implementing the present invention. Initially in
the process of FIG. 12, the product identifiers for the products to
be purchased are received by the POS terminal (step 120).
Typically, the product identifiers are entered into the POS
terminal by using a bar code scanner that is in communication with
the POS terminal to read bar codes on the products. It is noted
that machine readable indicia other than bar codes may be utilized
to identify products in accordance with the invention. Of course,
data identifying the products may also be entered by manually
entering the product identifier into the POS terminal using a
keyboard or by other known processes.
[0112] Next, at step 122, the POS terminal retrieves the "retail"
(i.e., non-discounted) prices for the products represented by the
product identifiers received at step 120. This pricing information
is obtained from the central server 54, and particularly from the
price database 86 shown in FIG. 3. The step 122 may comprise the
POS terminal retrieving the retail prices for the products once all
of the product identifiers for a given transaction have been
received or the POS terminal may retrieve the retail price for each
product as the corresponding product identifier is received. Then,
at step 124, the POS terminal 52 calculates an initial purchase
total for the transaction by totaling the retail prices for the
products that are being purchased in the transaction.
[0113] Following step 124 is a decision block 126, at which it is
determined whether the initial purchase total calculated at step
124 is at least equal to the threshold purchase total which
qualifies for gold tier pricing. In the example illustrated in FIG.
6A, the threshold purchase total for the gold pricing tier is $150,
and if this amount is equaled or exceeded by the initial purchase
total, then the gold tier prices for each product in the
transaction are retrieved from the price database, as indicated at
step 128.
[0114] If at step 126 it was found that the initial purchase total
does not equal or exceed the threshold purchase total for the gold
discount pricing tier, then it is determined, at decision block
130, whether the threshold purchase total for the silver discount
pricing tier is satisfied. If so, the corresponding prices of the
silver tier are retrieved from the price database for each product
of the transaction (step 132). If it is found at step 130 that the
threshold purchase total for the silver tier is not satisfied, then
a decision block 134 follows block 130. At block 134 it is
determined whether the threshold purchase total for the bronze tier
has been satisfied. If so, the bronze tier price for each product
of the transaction is retrieved from the price database (step
136).
[0115] Assuming that any one of the three threshold purchase total
is satisfied by the purchase total, then a step 138 is performed
after the applicable one of steps 128, 132 and 136. At step 138 the
purchase total is recalculated using the appropriate prices
retrieved at step 128, 132 or 136, as the case may be. Essentially,
the recalculation referred to at step 138 consists of assigning the
appropriate discount price to each product of the transaction and
totaling the discount prices. Although the term "discount" was used
in the preceding sentence, it will be recognized that in some cases
the price for a product in one or more of the discount pricing
tiers may be the same as the retail price for the product.
[0116] After step 138, the POS terminal takes whatever further
actions may be required to complete the transaction, as indicated
at step 140. For example, the POS terminal may calculate a sales
tax based on the transaction total. In addition, as part of step
140 the POS terminal may print a receipt for the transaction,
process a credit card payment, or calculate change from an amount
tendered.
[0117] It should also be noted that in the event that none of the
discount pricing tier thresholds are met, step 140 is performed
immediately after step 134. In the latter case, the initial
purchase total for the transaction, based on the retail prices for
the products purchased, is used as the transaction total, and the
activities carried on in step 140, including calculation of sales
tax and credit card payment processing, etc., are based on
non-discounted (i.e. retail) prices for the products purchased.
[0118] The foregoing discussion of the process of FIG. 12 has not
explicitly taken into account the information which may be
displayed on the display device 64 (FIG. 2) of the POS terminal.
The present invention contemplates that, during steps 120-124,
information corresponding to the products to be purchased and the
retail prices therefor may be displayed in accordance with
conventional practice as the product identifier for each product is
received and the corresponding retail price retrieved. In addition,
the initial purchase total may be displayed with an additional
legend such as "total before any discount earned". Then, if it is
determined that one of the discount pricing tiers is applicable,
the display device 64 may rapidly display a sequence of the
pertinent discount prices for each of the products purchased as the
relevant one of steps 128, 132 and 136 is performed. During step
138, the recalculated purchase total may be displayed with a legend
such as "adjusted total based on gold prices" (or silver or bronze,
as the case may be).
[0119] To summarize the process illustrated in FIG. 12, a first
(retail or non-discounted) price is retrieved for each product to
be purchased, and is used to calculate an initial purchase total.
If the purchase total is at least equal to a threshold purchase
total which corresponds to a discount pricing tier, then the
respective prices from the discount pricing tier for each product
to be purchased are retrieved. The prices from the relevant
discount pricing tier may be regarded as "second" prices for the
products, and these second prices are totaled to calculate a
reduced purchase total for the transaction.
[0120] By using a technique of this type, which is based on one or
more discount prices assigned to products to be purchased, in
addition to a non-discounted price, the retailer can precisely
tailor its discounting plan to maximize the plan's effectiveness
while reducing or eliminating discounts on products which have a
low profit margin.
[0121] According to one modification of the discount technique
illustrated in FIG. 12, the reduced purchase total calculated at
step 138 may be compared with the threshold for the discount
pricing tier which was applied, and the discount pricing may be
modified or reversed if the reduced purchase total fails to satisfy
the threshold purchase total for the corresponding discount pricing
tier.
[0122] Another embodiment of the present invention contemplates
that the format of the shelf display shown in FIG. 6 may be
modified to present the discount pricing tiers in terms of "cents
off" or "percent off". In particular, for cream cheese, the gold
price could be stated as "30 off"; the silver price as "15 off";
and the bronze price as "5 off". (Of course, another phrasing such
as "save 3 " could also be used.)
[0123] It is also contemplated to change the format of the price
database 86 so that the discount prices for each product are
defined in terms of an amount or percentage to be subtracted from
the retail price.
[0124] In the embodiment of the invention which was described with
reference to FIG. 12, the criterion used to determine whether
discount pricing should be applied was the initial purchase total
of the transaction, as calculated based on non-discounted
prices.
[0125] FIG. 13 illustrates an alternate embodiment of the
invention, in which the discount qualification criterion is the
number of products of a certain type which are included in the
transaction. For example, qualification for a discount may depend
on the number of products of a certain brand, such as a store
brand, which the customer purchases at one time. The POS terminal
may determine which products are store brand products by, for
example, the product identifier of the product (e.g. one or more
digits of the product identifier identifies the product as a store
brand product). According to a more specific example, for the
"gold, silver, bronze" pricing scheme referred to above, purchase
of 10 store brand products would be required to qualify for the
gold pricing tier, while purchase of 8 store brand products would
be required for the silver prices and 6 store brand products for
the bronze prices.
[0126] The process of FIG. 13 begins with step 200, in which, as in
step 120 of FIG. 12, product identifiers are received for each
product to be purchased.
[0127] When the product identifiers for every product in the
transaction have been received by the POS terminal, the total
number of qualifying products is determined (step 202). For
example, the POS terminal cashier may actuate a "total" button on
the POS terminal to indicate that no more product identifiers are
to be received, which triggers the process of FIG. 13. In the
example which was referred to above, it was assumed that qualifying
products were those which carry a store brand. On the basis of the
total number of store brand products included in the transaction, a
decision block 204 is carried out. The POS terminal may determine
whether a product is a store brand product based on, for example,
the product identifier (e.g. one or more digits of the product
identifier could identify the product as a store brand product). Of
course, those skilled in the art of POS systems will recognize many
ways of determining the number of store brand products included in
a transaction. At block 204, it is determined whether the number of
store brand products included in the transaction is at least equal
to the threshold number of store brand products for the gold
discount pricing tier. If so, the respective gold discount price
for each product in the transaction is retrieved, as indicated at
step 206.
[0128] If at step 204 the number of qualifying (e.g. store brand)
products is not found to satisfy the threshold number of qualifying
products for the gold discount pricing tier, then a decision block
208 follows block 204. At block 208 it is determined whether the
number of qualifying products is at least equal to the threshold
number of qualifying products for the silver discount pricing tier.
If so, the respective prices from the silver tier for each product
of the transaction are retrieved, as is indicated by step 210.
[0129] If the determination at block 208 is that at least the
threshold number of qualifying products are not included in the
transaction, a decision block 212 follows block 208. At decision
block 212, it is determined whether the number of qualifying
products is at least equal to the threshold required to qualify for
the bronze discount pricing tier. If such is the case, then the
respective bronze discount pricing tier price for each product of
the transaction is retrieved from the price database, as indicated
at step 214.
[0130] If the determination at block 212 is in the negative, then
the retail prices for each product in the transaction are
retrieved, as indicated at step 216. Following the applicable one
of steps 206, 210, 214 and 216 is a step 218, at which a final
purchase total for the transaction is calculated using the
applicable prices which were retrieved for the products in the
transaction. After step 218 other conventional processes required
to complete the transaction are carried out, as indicated in step
220, and as previously discussed in connection with step 140 in
FIG. 12.
[0131] In the process just described, it was assumed that if a
qualifying number of store brand products were purchased, then all
products in the transaction would be accorded discounted pricing
from the appropriate discount pricing tier. However, this process
may be modified so that the discounted prices are applied only to
the qualifying products themselves, e.g., only to store brand
products. If the embodiment of FIG. 13 is modified in this manner,
then retail prices would be applied to all products which do not
carry the store brand or otherwise non-qualifying products.
[0132] An advantage of the embodiment of FIG. 13 is that the
retailer is permitted to use a flexible discounting plan to promote
sales of certain products such as, for example, store brand
products, perishable products, or high margin products.
[0133] A further embodiment of the invention will now be described
with reference to FIGS. 10A, 10B, and 10C. In this embodiment,
instead of defining discount pricing tiers, with corresponding
prices in each tier assigned to each product available for
purchase, the price database defines the discounted prices in terms
of decrements to be applied to a retail price of a given product.
The decrements are applied on the basis of purchase total
thresholds and purchase total increments, which may be varied from
product to product and tier to tier. The price decrement also may
vary from product to product and from tier to tier. In one
variation of this embodiment, the price decrement for a given
product may increase as the purchase total increases. For example,
the system of the invention could decrement the retail price of the
product by 2 for every $1 increment in the purchase total between a
purchase total threshold of $50 and a purchase total of $100 and
then decrement the retail price of the product by 5 for every
subsequent $1 increment in the purchase total.
[0134] FIG. 14 illustrates a process which corresponds to an
embodiment of the invention which utilizes the pricing format
illustrated in FIGS. 10A, 10B, and 10C.
[0135] The process of FIG. 14 begins with steps 300, 302 and 304,
which are essentially the same as steps 120, 122 and 124 of FIG.
12. To recapitulate these steps, product identifiers for each
product to be purchased in the transaction are received by the POS
terminal (e.g. are input into the POS terminal via a bar code
scanner or keyboard by a cashier operating the POS terminal),
retail prices for each of the products corresponding to the
received product identifiers are retrieved from the price database,
and an initial purchase total for the transaction is calculated
using the retail prices.
[0136] Following step 304, the process of FIG. 14 enters a
processing loop which is applied to each product in the
transaction. In the first step of the loop, which is step 306, the
product identifier corresponding to the next (the first product at
the outset of the loop) product to be processed is selected from
the products included in the transaction. Specifically, the
purchase total threshold, the price decrement, the purchase total
increment and the minimum price for the product are all retrieved
in step 308 (e.g. from a database such as illustrated in FIG.
10B).
[0137] Following step 308 is a decision block 310. In decision
block 310, it is determined whether the purchase total for the
transaction, as calculated at step 304, is at least equal to the
"purchase total threshold" for the currently selected product
identifier. If not, the retail price for the product is stored as
the price to be applied to the current transaction for the selected
product. Then it is determined, at decision block 312, whether or
not there are further products to be considered in connection with
the transaction. If there are further products in the transaction,
the process of FIG. 14 loops back to step 306.
[0138] It will next be assumed that, at step 310, it was determined
that the initial purchase total calculated at step 304 was at least
equal to the "purchase total threshold" for the currently selected
product identifier. In that case, step 314 follows decision block
310. In step 314 a discounted price for the product represented by
the product identifier is calculated according to the formula set
forth below. This discounted price thus replaces the retail price
for the product within the current transaction and is determined by
the POS terminal to be the appropriate price for the product to be
applied to the current transaction. Of course methods other than
overriding the retail price may be recognized and utilized by one
of ordinary skill in the art in providing a calculated discounted
price to the customer in accordance with the invention. For
example, the difference between the retail price and the calculated
discount price may be determined by the POS terminal and applied to
the current transaction as a credit (i.e. deducted from the initial
purchase total). An example formula of how to calculate a discount
price for a product in accordance with the invention follows:
P.sub.D=P.sub.R-{(1+[(T-H)I]).times.D} (1)
[0139] where: [0140] P.sub.D=the discounted price to be calculated
at step 314; [0141] P.sub.R=the retail price for the product;
[0142] T=the initial purchase total calculated at step 304; [0143]
H=the purchase total threshold for the product; [0144] I=the
purchase total increment for the product; [0145] D===the price
decrement for the product; and [0146] the square brackets ([ ])
denote the largest non-negative integer that is less than the
quantity within the square brackets.
Example A
[0147] To present an example of the above calculation, assume that
the selected product identifier is "P135" (using the data of FIGS.
10B and 10C for this example) and the initial purchase total (T)
calculated at step 304 was $75.32. Then the formula set forth in
equation (1) is applied, using the information presented for
product P135 in FIGS. 10B and 10C, as follows:
P D = 2.99 - { ( 1 + [ ( 75.32 - 50.00 ) / 10.00 ] ) .times. 0.05 }
= 2.99 - { ( 1 + [ 25.32 / 10.00 ] ) .times. 0.05 } = 2.99 - { ( 1
+ 2 ) .times. 0.05 } = 2.84 ##EQU00001##
[0148] Consequently, in this example the discounted price P.sub.D
calculated for the product in step 314 is $2.84.
[0149] If the initial purchase total had been between $50.00 and
$60.00, the formula of equation (1) would yield a discounted price
P.sub.D of $2.94 for the product represented by product identifier
P135 (in accordance with the illustrative data of FIGS. 10B and
10C).
[0150] Following step 314, the discounted price calculated in that
step is compared with the minimum price for the product under
consideration, as indicated at decision block 316. If the
discounted price is less than the minimum price, then the price to
be applied to the product is set to the minimum price, as indicated
by step 318. Otherwise the price to be applied to the product is
the discounted price calculated at step 314, as is indicated by
step 320.
[0151] Following either step 318 or step 320, as the case may be,
the process advances to decision block 312, at which it is
determined whether there is another product in the transaction to
be considered. If another product is included in the transaction
that has not yet been processed, the process loops back to step
306. Otherwise, the process advances from decision block 312 to
step 322, at which a final purchase total to be applied to the
transaction is calculated by substituting for the retail price of
each product any discounted price for the product that was set
according to step 318 or step 320.
[0152] It will be noted that the discount technique illustrated in
FIGS. 10A-10C and FIG. 14 provides even greater flexibility than
the technique exemplified by the process of FIG. 12. In the
technique of FIGS. 100A-10C and FIG. 14, there are four separate
variables that may be adjusted for each product. These are (i)
qualifying threshold ("purchase total threshold"), (ii) price
decrement, (iii) purchase total increment, and (iv) minimum price.
With these four variables, the retailer has almost complete freedom
to adjust the discounting plan according to the retailer's
promotional goals, and the profitability of each product. It is
contemplated to modify the discounting technique illustrated in
FIGS. 10A-10C and FIG. 14 in a number of ways. For example, one or
more of the four variables can be made uniform among all of the
products. As another variation, the formula applied at step 314 can
be changed. The following is an example of a formula that could be
applied instead of the formula of equation (1):
P.sub.D=P.sub.R-{[(T-H)/I].times.D}(2)
[0153] If the formula of equation (2) were applied to the Example A
given above, the discounted price P.sub.D for the product P135
would be 2.94 .
[0154] In the discounting techniques which have been described up
to this point, qualification for discount pricing has depended upon
a characteristic of the transaction to which the discount pricing
is to be applied. However, the present invention contemplates using
other types of criteria to determine qualification for discounting.
Such criteria may include a customer's purchasing history or the
purchasing history of a group or "team" with which the customer is
associated.
[0155] If purchasing history is to be used to determine eligibility
for discounted prices, then it becomes desirable to maintain a
transaction database 90 of the type referred to in connection with
FIG. 3. FIG. 15 illustrates an example of a single transaction
record 400 which is included in the transaction database 90. The
fields included in the transaction record 400 include a transaction
identifier 402 (which may comprise, for example, a string of
alphanumeric digits that uniquely identify the transaction), a
customer identifier 404 (which may comprise for example, a string
of alphanumeric digits that uniquely identify the customer or the
team that the customer is associated with), an operator identifier
406 which identifies the check-out clerk who handled the
transaction, and a POS identifier 408 which identifies the POS
terminal 52 at which the transaction was processed. Additional
fields in the transaction record 400 include the purchase total for
the transaction (field 410) and a field 412 which indicates the
date and time at which the transaction occurred. The balance of the
transaction record 400 is made up of data entries 413 which
identify the products purchased and the price paid therefor. It is
seen from FIG. 15 that each entry has a data element in a product
identifier column 414 and another data element in a price paid
column 416.
[0156] Another component for a purchase-history-based discounting
plan is the customer database component 92 shown in FIG. 3. FIG.
16A illustrates one simplified example of such a customer database.
FIG. 16A indicates that the customer database 92 is made up of data
entries 500, each of which includes a respective data product in
three columns, namely a customer identifying code 502, customer
name 504 and a column 506 which contains an indication of a
discount pricing tier for which the customer has qualified. The
manner in which a customer qualifies for a discount pricing tier
may be determined in a number of ways. For example, qualification
for a particular discount pricing tier may be based on the sum of
purchase totals spent by the customer during the previous calendar
month. According to one example, customers whose sum of purchase
totals is equal to or greater than $100 in the preceding calendar
month would be eligible for the gold discount tier. Customers who
purchased at least $75 during that period of time but less than
$100 would qualify for the silver tier, and those who purchased at
least $550 but less than $75 during that time period would qualify
for the bronze tier.
[0157] Customers who purchased less than $50 during the qualifying
period would pay the retail prices for the products purchased.
[0158] It should be understood that the qualifying period may be
set to be shorter or longer than a month, that the qualifying
amounts referred to above can be varied in many ways, and that the
time period need not be tied to a calendar month or week, but could
be rolling from day to day so that, for example, the customer's
qualification to receive discounted prices on a given day may
depend on the quantity of purchases that he or she made in the last
30 days, the last 7 days, or any other period of time. The present
invention also contemplates that, instead of basing discount
qualification on the sum of purchase totals for a period of time,
the qualification could be based on the average value per
transaction during a given period. If a "rolling" qualification
period is used, the current transaction itself could be used to
update the customer's purchasing history and to therefore grant or
withhold qualification for a particular discount pricing tier on
the basis of the current transaction taken into consideration with
previous transactions. Additional methods of updating and applying
a discount that a customer qualifies for based on their purchasing
history is disclosed in applicant's co-pending U.S. patent
application entitled "METHOD AND APPARATUS FOR DETERMINING A
PROGRESSIVE DISCOUNT FOR A CUSTOMER BASED ON THE FREQUENCY OF THE
CUSTOMER'S TRANSACTIONS", U.S. application Ser. No. 09/166,267,
filed Oct. 5, 1998, which is incorporated by reference herein as
part of the present disclosure, U.S. application Ser. No.
09/166,267 discloses, for example, conditions associated with a
customer rating that corresponds to a discount that have to be
satisfied, in order for the customer to qualify for the discount.
U.S. application Ser. No. 09/166,267 further discloses methods of
updating a discount that a customer is entitled to based on their
previous transactions (i) at the time of a transaction, or (ii)
periodically; and methods of updating a discount that a customer is
entitled to based on the products included in the customer's
transaction.
[0159] FIG. 16B presents an alternate format for a customer
database 92. This format includes an additional column 508 in which
some details of the customer's purchasing history are presented. In
the example shown in FIG. 16B, an entry for "average monthly
purchase total" is shown in column 508. This figure could
represent, for example, the monthly average of purchases by the
customer during the most recent three calendar months.
[0160] As noted above, the discount pricing tier for which a
customer qualifies may be determined on the basis of a purchasing
history of a "team" (e.g. a group of customers) to which the
customer belongs. To implement this type of discounting plan, a
team database 94 (FIG. 3) should also be maintained in addition to
a customer database 92. FIGS. 17A and 17B respectively present
simplified examples of formats for a team database 94 and a
customer database 92 to be used in connection with a team shopping
plan.
[0161] In the team database 94 shown in FIG. 17A, data products 520
each have two attributes, of which the first, corresponding to
column 522, is an identifier for the team, and the second,
corresponding to column 524, is the discount level for which the
team qualifies. A method and apparatus for managing a group reward
program whereby a group of customers is registered with a retail
outlet as a shopping group is disclosed in applicant's co-pending
U.S. patent application entitled "POINT-OF-SALE SYSTEM AND METHOD
FOR THE MANAGEMENT OF GROUP REWARDS", U.S. application Ser. No.
09/118,414, filed Jul. 17, 1998, which is incorporated by reference
herein as part of the present disclosure. U.S. application Ser. No.
09/118,414 discloses a system that uses point-of-sale terminals to
monitor transactions processed according to a group reward program,
wherein the system (i) stores a plurality of customer identifiers
that correspond to customers that register with the group reward
program; (ii) assigns a group identifier to the group of customers;
(iii) stores and applies reward rules that apply to the groups;
(iv) tracks the performance of the group as compared to the reward
rules; (v) determines whether the group is eligible for a reward
(e.g. by performing a periodic reconciliation process for each
stored group identifier; and (vi) performs a redemption process of
any rewards the group is eligible for. Examples of reward rules
include a number of purchases to be made by a group, a dollar value
of purchases to be made by a group, a number of purchases to be
made by the group within a predetermined period of time or before a
predetermined date, specific products to be purchased by the group,
and a specific time or times during which purchases must be made by
the group.
[0162] The customer database format shown in FIG. 17B is similar to
that shown in FIG. 16A. In FIG. 17B the "pricing tier" column 506
of FIG. 16A is replaced with a column 510 which consist of team
identifying codes to indicate the team to which the customer
belongs. It will be recognized that the data contained in the
databases of FIGS. 17A and 17B can be processed to determine for
each customer the discount pricing tier for which the customer
qualifies.
[0163] FIG. 18 is a flowchart which illustrates a process carried
out according to an embodiment of the invention in which customers
qualify for discounted pricing based on their purchasing history.
According to the process shown in FIG. 18, the POS terminal begins
processing a transaction by first receiving data which identifies
the customer (step 540). For example, customers participating in
the discount plan may carry an identification card which includes a
magnetic stripe or a bar code to indicate the customer's
identification code. In such cases, step 540 can be carried out by
using a bar code reader or a magnetic stripe reader to read the
customer's identification card. As an alternative, the
identification card may simply have printed thereon an ID code or
the customer's name, and the ID code or customer's name can then be
entered into the POS terminal by using the keyboard. The customer
could also carry a "smart card" from which the POS terminal reads
identifying information by wireless communication.
[0164] Once the customer identifier has been entered, step 542
follows, in which the POS terminal retrieves from the server 54 the
corresponding record for the customer which is maintained in the
customer database 92. Next, at step 544, the POS terminal 52 and/or
the server 54 extracts from the customer record the data in column
506 for that customer, namely data which indicates the pricing tier
for which the customer is qualified.
[0165] The process of FIG. 18 then continues with a loop consisting
of steps 546 and 548 and a decision block 550. In this processing
loop, the products to be purchased in the transaction are processed
in a serial fashion. At step 546 the product identifier is entered
by, for example, using a bar code reader to read a bar code on the
product. Then, at step 548, the corresponding price for the
product, in the pricing tier for which the customer is qualified,
is retrieved.
[0166] At decision block 550 it is determined whether another
product is to be included in the transaction. If so, the process
loops back to step 546. Otherwise, step 552 follows decision block
550. At step 552, the prices determined for the products presented
for purchase are totaled and other steps required to complete the
transaction are carried out.
[0167] To summarize the process illustrated in FIG. 18, the
customer is identified at the beginning of the transaction, his or
her qualification for discount pricing is determined, and then each
product purchased in the transaction is priced according to the
pricing tier for which the customer is qualified.
[0168] FIG. 19 illustrates a process carried out in accordance with
the invention to update a customer's purchasing history. For
example, the process of FIG. 19 might be carried out as a batch
process at the end of each week or month, depending on how the
discount plan operates. The process is preferably performed by the
central server 54 (FIG. 3) or by another server (not shown) in
communication with the central server 54.
[0169] Let it be assumed for the purposes of this example that the
discount plan is based on the sum of purchase totals completed by
the subject customer during, for example, a calendar month. In that
case, at the end of each month, the process of FIG. 19 would be
carried out.
[0170] According to a first step (reference numeral 560) in FIG.
19, a customer record (i.e., one of the data entries 500 shown in
FIG. 16A) is retrieved from the customer database 92 by the central
server 54. The central server 54 then retrieves from the
transaction database 90 all transaction records 400 (FIG. 15) for
the customer which have a date since the most recent updating of
the customer database. In particular, the central server 54
extracts from the customer records the purchase totals (product
410) for each of the transactions.
[0171] Referring once more to FIG. 19, the purchase totals for the
retrieved transactions are added together to establish the total
amount spent by the customer during the relevant period. Then, as
indicated at step 566, it is determined on the basis of the total
amount spent during the period, what discount pricing tier the
customer is qualified for. On the basis of this determination, the
"pricing tier" entry for the customer in the customer database 92
is updated at step 568 by writing the appropriate indication into
column 506 (see FIG. 16A). The central server 54 then retrieves the
next customer's record from the customer database 92 (step 570) and
the loop which commences with step 562 is repeated.
[0172] As an alternative to the batch-processing approach
illustrated in FIG. 19, the invention also contemplates that the
customer database can be updated in essentially "real time", i.e.,
each time a transaction takes place. A process which illustrates
this alternative will now be described with reference to FIG. 20.
The customer is identified at the beginning of the transaction when
the customer identifier is received by the POS terminal in step
580. The customer's record is retrieved from the customer database
based on the retrieved customer identifier and the pricing tier for
which the customer is qualified is retrieved from that record in
step 582. The product identifiers of the products included in the
present invention are received in step 584. In step 586 the
appropriate prices for the received product identifiers are
retrieved from the pricing database based on the pricing tier
determined in step 582, these prices are summed to determine the
purchase total for the current transaction.
[0173] For the purposes of the process illustrated in FIG. 20, it
is assumed that discount pricing tier qualification is based upon a
customer's average purchase level during a predetermined period of
time, such as the last month. The last three steps of FIG. 20
indicate how the average purchase figure is updated based on the
current transaction. In step 588 the purchase totals of the
customer's previous transactions in the relevant time period are
retrieved from the customer's record of the transaction database
(based on the customer identifier). At step 590, the average
purchase total stored in the customer's record (for example, as
represented by field 508 in table 92 of FIG. 16B) of the customer
database is updated by summing the purchase totals of the
transactions retrieved in step 588 and the current transaction, and
then dividing by the number of transactions. The average purchase
total is stored in the customer's record of the customer database
and the discount pricing tier for which the customer is qualified
is determined on the basis of the updated average purchase total
and stored in the customer's record of the customer database in
step 592. The process of updating the customer's average purchase
total has been described as being initiated upon the completion of
a current transaction by the customer. It will be understood by
those skilled in the art that such an update of the average
purchase total can be performed via different methods, such as on a
periodic basis (e.g. once a week). The process of updating a
customer's average purchase total may also be completed in a batch
process such that all or some of the customer's records are
processed essentially at the same time. It should also be
understood that if the average purchase total is calculated for a
predetermined length or period of time (e.g. monthly) then at the
end of such a period of time the average purchase total would be
reset to a default value (e.g. zero) and the process started again
for the new period (e.g. the next month). When the average purchase
total is reset, the discount pricing tier that the customer is
qualified for may be set to (i) the same discount pricing tier that
the customer had been qualified for at the end of the previous
period of time, (ii) rest to a default discount pricing tier, or
(iii) set to the retail pricing tier.
[0174] Up to this point, embodiments of the invention have mainly
been described in the context of a physical retail outlet (e.g. a
supermarket). However, the practices of the present invention are
also applicable to a number of other types of retail outlets. For
example, the teachings of the present invention could be
advantageously applied in the environment of a quick service
restaurant; e.g., with the goal of increasing the average purchase
per visit. According to one example, an operator of a quick service
restaurant may choose to define only a single discount tier of
prices, thereby assigning only a retail price and a discounted
price to each product. The quick service restaurant operator may
set a fairly low threshold purchase total for a transaction, say
$10, for the discount pricing to apply. In such a case, the
operator of the quick service restaurant might also find it
advantageous to display at the POS terminals the amount of an
additional purchase that the customer needs to make in order to
qualify for discount pricing. In this example, assume that the
purchase total threshold to qualify for discount pricing is $10,
and that the customer has ordered a number of products whose retail
prices sum up to a purchase total $9.50. The POS terminal can be
programmed to display information such as that shown in FIG. 21 to
indicate that the customer needs to spend another $0.50 to qualify
for discount pricing. The POS terminal could further be programmed
to determine an appropriate product to suggest to the customer and
display the suggestion for the product in the form of a prompt to
the cashier operating the POS terminal. The cashier operating the
POS terminal could therefore suggest to the customer an additional
product that could be purchased to reach the discount pricing based
on the displayed prompt.
[0175] The present invention also contemplates application of the
multi-tier product pricing techniques disclosed above to retail
outlets other than retail stores. One type of retail outlet for
which the practices of the present invention may be particularly
advantageous is an Internet shopping sites. A particular
application of the present invention to an Internet shopping site
(which will be referred to as a Web site herein) will now be
described with reference to FIGS. 22-25.
[0176] FIG. 22 is a highly schematic representation of the computer
hardware needed to carry out this aspect of the invention. All of
this hardware may be of conventional design. The hardware includes
a Web server computer 600, which is connected to the Internet
(represented by reference numeral 602) and is programmed to host a
Web site. In addition, the Web server 600 is programmed to perform
functions in accordance with the present invention, as will be
described below. It is also contemplated that the Web server 600
would maintain a product and price database. Of course, it is
possible that the products available for purchase through the Web
server 600 are different from the grocery products listed in the
examples referred to above. The products available for sale through
the Web server 600 may be books, musical recordings, videos,
clothing, computers and computer peripherals, services such as
carpet cleaning, or any other type of product.
[0177] FIG. 22 also shows a customer device 604 connected to the
Internet 602. The customer device may be any device that allows the
customer to access the Web server via the Internet, such as a
personal computer (PC), personal digital assistant (PDA), cellular
phone, or pager. As will be understood by those who are familiar
with operation of the Internet, the customer device 604, when
connected via the internet 602 to the Web server 600, operates in a
"client" mode to exchange data with the Web server 600.
Accordingly, the customer device 604 will sometimes be referred to
as a "client computer". Although only one customer device 604 is
shown as being in communication with the Internet 602, it will be
understood that any number of customer devices may be connected to
the Internet and access the Web server 600. In addition, the Web
server 600 is likely to be arranged to serve a number of customer
devices 604 simultaneously so that more than one customer may place
orders with the Web server 600 at any given time.
[0178] Few details of the customer device 604 are shown in FIG. 22,
but it is to be appreciated that in most cases the customer device
604 will have all of the components usually found in a computer
(e.g. processor, display component, input component, device
drivers, communication port). For present purposes, only a display
component 606 and an input component 608 (e.g. a keyboard and/or
mouse are shown. The customer device 604 may also take the form of
a so-called Web-access "appliance", i.e., a device which can be
attached to a television set to enable a viewer to navigate the
Internet and to display downloaded information on the television
screen.
[0179] FIG. 23 is a flowchart which illustrates an example of a
process performed by the Web server 600 in accordance with an
embodiment of the invention. In the example illustrated by FIG. 23,
it will be assumed that the Web server 600 is hosting a Web site
for selling bicycling accessories, and that the Web server stores a
price database with only two discount pricing tiers--retail prices
and one tier of discount prices.
[0180] It should be noted that although the following processes are
described as being performed by the Web server 600, the processes
may alternately be performed by one or more servers that are in
communication with the Web server 600 or by a combination of the
Web server 600 and one or more additional servers.
[0181] According to an initial step 650 in FIG. 23, the Web server
600 receives an attempt by the customer device 604 to access the
shopping Web site hosted by the Web server 600. As is known to
those who are skilled in the art of the Internet, including users
thereof, a customer may perform the access attempt using the
customer device 604 by entering the Web address for the server 600
into the appropriate field of their browser, or by selecting a
hyper-link for the shopping Web site.
[0182] When the Web server 600 detects the access attempt from the
customer device 604, the Web server 600, in step 652, transmits to
the customer device 604, via the Internet, information to be
displayed on the customer device 604. One of the purposes of the
information is to permit the user of the customer device 604 to
perform a shopping function. An example of the resulting screen
display that may be provided on the display component 606 of the
customer device 604 is shown in FIG. 24.
[0183] Referring now to FIG. 24, except for the discount
qualification information which will be described below, the screen
display shown in FIG. 24 may resemble conventional screen displays
provided in response to accessing a shopping Web site. The screen
display of FIG. 24 includes an upper display section of the screen
624 which includes product listings 626 and 628. The product
listings 626 and 628 display information on the products currently
included in the customer's order. At the right-hand side of the
upper display section 624 a scroll bar 630 is provided to permit
the customer to scroll upward or downward to view additional
product listings or other information displayed on the screen. Each
of the product listings includes a product description 100, a
product identifier 98, a retail price 108 and a discounted price
106. Those of ordinary skill in the art will recognize how the
product listing portions 626 and 628 of the screen display of FIG.
24 can be generated from corresponding data entries in the price
database referred to above.
[0184] Also included in the display section 624 is a "shop some
more" button 632 which may be actuated by the customer using a
cursor (not shown) to indicate that the customer wishes to continue
shopping (i.e. add more products to his order). Although not shown
in FIG. 24, it will be understood that images and additional
description of the products may also be included in the display.
Although only two product listings are shown in FIG. 24, it will be
understood that the format of the screen display may be modified so
that a larger number of product listings are displayed at a given
time.
[0185] The screen display of FIG. 24 also includes a lower display
section 640 which includes a purchase total field 642 and a
discount qualification notice 644. The purchase total field 642
indicates the total dollar amount of products that the customer has
ordered during the session. FIG. 24 displays a purchase total of
$55.38 (the sum of the retail price of the products included in the
customer's order plus an exemplary 6.5% sales tax).
[0186] The discount qualification notice 644 indicates to the
customer the dollar amount of additional purchases that the
customer needs to make in order to qualify for discount pricing.
For the purposes of this example, it is assumed that the purchase
total required for discounted pricing is $60.00. Accordingly, the
customer is informed via the discount qualification notice 644 that
he or she needs to spend an additional $4.62 ($60.00-$55.38=$4.62)
to qualify for discount pricing.
[0187] The lower display section 640 of the display also includes a
"submit order" button 646 that the customer may actuate to indicate
that he or she has completed selection of the products to be
ordered and, for example, is ready to provide payment information
to the Web server 600.
[0188] Referring again to FIG. 23, a decision block 654 follows
step 652. At decision block 654 it is determined whether a product
has been selected for purchase by the customer operating the
customer device 604. If so, the transaction information for the
current transaction is transmitted for display by the customer
device 604 in step 656. Displaying the transaction information may
comprise, for example, retrieving the product identifier
corresponding to the selected product from the product database and
entering it into the product identifier field 98 of the display
illustrated in FIG. 24 as well as adding a product listing such as
the product listings 626 and 628 in FIG. 24 to the upper display
section 624 (FIG. 20). As described above, the product listing may
include the selected product description, the retail price of the
product, and the discount price of the product.
[0189] At step 658, the Web server 600 then generates an initial
purchase total for the transaction based on the retail price for
the product and any sales tax applicable. The process then
continues to decision block 660, in which step the Web server 600
determines whether the transaction qualifies for discount pricing
(e.g. it is determined whether the initial purchase total is at
least equal to a threshold purchase total). If the transaction does
qualify for discount pricing, the process proceeds to step 662,
wherein a purchase total is calculated for the transaction using
the discount price for the product included in the transaction.
Once the purchase total using the discount price is calculated, the
displayed transaction information is updated in step 664 using the
purchase total calculated in step 662. For example, the purchase
total calculated in step 662 is entered into the purchase total
field 642 of the lower display section 640 (FIG. 24).
[0190] In addition, the discount qualification notice 644 may be
updated to include a notice such as "Congratulations! You have
qualified for discount pricing! The order total reflects the
discount prices for the products you have ordered."
[0191] If, in decision block 660, it is determined that the initial
purchase total does not qualify for discount pricing, the process
continues to step 666. In step 666 the additional amount that the
customer needs to spend in order to qualify for discount pricing is
determined. The additional amount that the customer needs to spend
may be determined, for example, by subtracting the purchase total
from the threshold purchase total associated with discount
pricing.
[0192] The process then continues to step 664, wherein the
displayed transaction information is updated. Updating the
displayed transaction information in this case may comprise
displaying the initial purchase total in the purchase total field
642 and displaying the additional amount determined in step 666 in
the discount qualification notice 644 of the lower display section
640 (FIG. 24). The process continues from step 668 to step 670.
[0193] In step 670 it is determined whether the order has been
submitted (e.g. it is determined whether the customer has indicated
that he or she is finished with the transaction by actuating the
"submit order" button 646). If the customer has submitted the
current order the process continues to step 672, wherein the
transaction processing is completed. Completing the transaction
processing may comprise steps such as receiving a payment
identifier and shipping address from the customer and submitting
the order for shipping to the customer. If, in decision block 670,
it is determined that the customer has not submitted the order
(e.g. the customer has actuated the "shop some more" button 632 on
the upper display section 624 of FIG. 24) the process loops back to
step 654 and it is determined whether another product has been
selected by the customer and added to the current transaction. If
there is another product selected by the customer, steps 656
through 670 are repeated to take into account the newly added
product (e.g. an initial purchase total is calculated based on the
retail price of the previously selected product and the newly
selected product) in addition to the previously selected product.
It will also be understood that if a transaction qualifies for
discount pricing based on a current purchase total, discount
pricing will be applied to all subsequent products added to the
transaction.
[0194] Although the process of FIG. 23 was described with the
assumption that there was only one discount pricing tier available,
it is understood that a number of discount pricing tiers other than
one may be provided. If multiple discount pricing tiers are
utilized the process of FIG. 23 may be slightly adjusted. For
example, rather than determining whether the initial purchase total
qualifies for a discount pricing, step 660 may comprise determining
whether the initial purchase total qualifies for any of the
available discount tiers and, if so, which one. Additionally,
multiple discount pricing tiers of discount prices can be stored in
the price database, and displayed as part of the product listings
626 and 628. In addition, the discount qualification notice 644
would be augmented to indicate the various dollar amounts required
to qualify for respective discount pricing tiers.
[0195] Furthermore, although the Internet shopping example
described above calls for qualification for discount pricing based
on the total amount ordered in the transaction, it should be
understood that the purchasing history discounting approaches
described above in the retail store context can be adapted for use
in an Internet shopping context. It is also contemplated to base
the discount pricing for the shopping Web site on the number and of
qualifying products purchased, as in the embodiment of FIG. 6C.
[0196] The embodiments of the invention portrayed in FIGS. 22-25
are particularly attractive to a retailer which operates a shopping
Web site, because the discount qualification notice 644 in FIG. 24
is a constant encouragement to the customer to keep the order
transaction open and to order additional products in order to reach
the threshold purchase total in order to qualify for discount
pricing. As a result, the discounting approach of this invention
can help the retailer to increase the average size of the orders
received through the shopping Web site while maintaining margins
that are typically sacrificed in prior art bulk discount
programs.
[0197] The product discounting techniques of the present invention
can also be applied advantageously in the context of a
telephone-order catalog operation. FIGS. 25 and 26 illustrate an
application of the invention in this environment.
[0198] FIG. 25 schematically illustrates a catalog order-taking
facility 700 that is in communication with customer telephone
devices 716 via a public switched network 714. The facility 700
includes a central server 702. The central server 702 may store a
program and a database (not shown) that preferably includes at
least the price database 86 and the condition database 88 referred
to above in connection with FIG. 3.
[0199] The facility 700 also includes a number of customer service
stations 706. At each station 706 there is provided a computer
terminal 708 (or another type of equipment that allows customer
service personnel to access product information stored at the
central server 702) and a telephone terminal 710 (or another type
of equipment that allows customer service personnel to communicate
with customers regarding their orders). The computer terminals 708
are connected to the server 702 by a data network 712.
[0200] The telephone terminals 710 may comprise a "handset"
telephone or a headset device to be worn by the customer service
personnel who work at the customer service stations 706. The
telephone terminals 710 are connected to the public switched
telephone network 714 to receive telephone calls initiated from
customer telephone devices 716. In accordance with conventional
practice, customers may initiate communication with the catalog
order-taking facility 700 by dialing a toll-free number.
[0201] For the purposes of this example, it will be assumed that
the operator of the facility 700 has printed and distributed
catalogs advertising the products to be sold through the facility.
Preferably the catalog lists for each product to be sold both a
retail price and at least one additional price which corresponds to
a discount pricing tier.
[0202] FIG. 26 is a flowchart which illustrates a process carried
out at the order-taking facility 700 to process an order for
products placed by a customer via a telephone call (e.g.
communications are exchanged between the customer service
representative and the customer via the telephone terminal 710 and
a customer telephone terminal 716). Although the example provided
in FIG. 26 contemplates only one discount pricing tier, it will be
evident that the process of FIG. 26 can be adapted to accommodate
two or more discount pricing tiers.
[0203] In an initial step 740 shown in FIG. 26, a telephone call
from a customer operating a customer telephone device 716 is
received by the order-taking facility 700.
[0204] The customer service representative operating a customer
service station 706 exchanges communications with the customer via
the telephone connection and is informed by the customer of a
product which the customer wishes to order (step 742). The customer
service representative then enters a product identifier for the
product by a conventional activity such as entering data via a
keyboard (not shown) of the computer terminal 708 or selecting a
product displayed on the monitor (not shown) of the computer
terminal 708 (step 744). The computer terminal 708 or the central
server 702 then calculates, in step 746, an initial purchase total
for the order transaction on the basis of a retail price for the
product. Once the initial purchase total is calculated, it is
determined whether the initial purchase total is greater than or
equal to the threshold purchase total associated with a discount
price tier (decision block 748). If the initial purchase total does
qualify the transaction for discount pricing (i.e. the initial
purchase total is greater than or equal to the threshold purchase
total) the process proceeds to step 764, in which step the purchase
total is recalculated using the discount price for the product. If
the initial purchase total does not qualify the transaction for
discount pricing, the process proceeds to step 750.
[0205] In step 750, the computer terminal 708 or the central server
702 calculates a difference between the initial purchase total for
the transaction and a threshold purchase total required to qualify
for discount pricing. The absolute value of this difference is the
additional amount that the customer needs to spend in order to
qualify for discount pricing. The additional amount that the
customer needs to spend in order to qualify for discount pricing is
then displayed on the monitor (not shown) of the computer terminal
708 (step 752) so that the customer service representative can
advise the customer of the additional amount that the customer can
spend in order to receive discount pricing (step 754).
[0206] At this point, it is determined whether the customer wishes
to order another product (decision block 756). The customer may,
for example, inform the customer service representative of another
product he or she wishes to purchase or the customer service
representative may suggest a product to the customer and the
customer may agree to purchase the suggested product. For example,
the central server 702 may determine an appropriate product to
suggest to the customer based on, for example, (i) the initial
purchase total, (ii) the product already included in the customer's
order, (iii) the customer's previous purchases, or (iv) what
products the operator of the order-taking facility 700 wishes to
promote. If it is determined in decision block 756 that the
customer does not wish to add another product to the transaction,
the process proceeds to step 772, at which step the transaction
processing is completed. The completion of transaction processing
may comprise, for example, obtaining the payment information from a
customer and the shipping address to which the current order should
be shipped.
[0207] If it is determined in decision block 756 that another
product is added to the current transaction, the customer service
representative again enters a product identifier (step 758) into
the computer terminal 708 and the computer terminal 708 or the
server 702 recalculates the purchase total for the transaction
based on the retail prices for the products now included in the
customer's order (step 760). It is then determined, indecision
block 762, whether the purchase total for the transaction is at
least equal to the threshold purchase total required in order to
qualify for discount pricing. If not, the process loops back to
step 750.
[0208] If it is determined at decision block 762 that the discount
pricing threshold purchase total has been satisfied, then the
purchase total for the transaction is recalculated based on the
discount prices for the ordered products (step 764). In addition,
of course, the customer service representative may inform the
customer that he or she has qualified for discount pricing.
[0209] Following step 764 is a decision block 766, at which it is
determined whether the customer wishes to order another product. If
so, the customer service representative enters another product
identifier (step 768) into the computer terminal 708 and the
purchase total for the transaction is recalculated based on the
discount price for the newly added product (step 770). Of course,
if more than one discount pricing tier is available, the purchase
total may be calculated based on the retail prices for each product
after the addition of another product, a determination made on
which, if any, discount pricing tier the transaction qualifies for
based on the purchase total, and the purchase total may be
recalculated based on the appropriate discount pricing tier. The
process then loops back to decision block 766.
[0210] If at decision block 766 it is determined that the customer
does not wish to order another product, the process advances to
step 770. At this step the customer service representative obtains
payment information from the customer, such as a credit card
number, and also is advised by the customer as to where the order
should be shipped. Further computer processing for order
fulfillment and tendering of the credit card payment to a
collecting financial institution is also carried out.
[0211] The process just described in connection with FIG. 22 may be
based on oral communication between the customer and a customer
service representative. However, it is also contemplated to adapt
the process of FIG. 26 for use in a catalog order-taking facility
which employs an automatic voice response system. In this case,
some or all of the customer service stations 706 would be
eliminated and telephone calls from customers would be routed to a
voice response system (not shown) interfaced to the central server
702. The voice response system responds to the telephone call and
prompts the customer to enter product identifiers through the
keypad of the customer's telephone. The voice response system
confirms the ordered products and announces to the customer an
additional amount or amounts for the customer to purchase to
qualify for discount pricing. In the contemplation of the
invention, an automatic voice response system is to be considered
the equivalent of the customer service stations.
[0212] Many variations of the discounting techniques of the present
invention have been described above, but all share common
advantages. The retailer is able to provide the customers with
incentives to make more and/or larger purchases, while setting
discount prices for each product in a way that preserves
satisfactory profit margins. The retailer also enjoys much greater
flexibility in setting discount prices than has been available in
conventional discounting plans.
[0213] Those skilled in the art will recognize that the method and
apparatus of the present invention have many applications, and that
the present invention is not limited to the representative examples
disclosed herein. For example, rather than retrieving retail
prices, threshold purchase totals, and discount prices from a
database, such information may be stored directly on the products
themselves, in the format of, for example, a bar code or
microprocessors affixed to each product. Moreover, the scope of the
present invention covers conventionally known variations and
modifications to the system components described herein, as would
be known by those skilled in the art.
