Abstract: A computer-implemented discounting system suitable for use in conjunction with a point-of-sale transaction device. The discounting system includes a memory subsystem for storing information related to at least one promotion and a software module coupled to the memory subsystem. The software module receives promotional codes entered by consumers and determines if the promotional codes relate to the promotions for which information is stored in the memory subsystem. If so, the software module transmits discount information for the promotions related to the entered promotional codes to the point-of-sale transaction device. For each promotion, a promotional code, a promotion period, a product code, a discount amount, a promotional code count and a maximum number of promotional codes are stored in the memory subsystem.

Abstract: A method for comparative analysis of consumer response to product promotions which provide discounts during point-of-sale transactions. First and second promotional entries respectively related to first and second promotions for a product and each comprised of a promotional code and a discount are stored in a memory subsystem of a computer system. First and second counts of the total number of times the first and second promotional codes are received by the computer system are maintained in memory. Each time a consumer enters a promotional code on a keypad coupled to the computer system, the entered promotional code is compared to the first and second promotional codes. If the entered promotional code matches the fast promotional code, the first count stored is incremented by one and the first discount amount is transmitted to a point-of-sale transaction device coupled to the computer system.
