Abstract: A system for generating, in a retail store, a printable discount coupon image solely in response to a customer's action concerning the purchase of an item. The system includes at least one customer checkout terminal, a store controller, a file for storing the terms of at least one coupon deal in which a discount coupon image is generated upon the purchase of a triggering product. The system identifies the triggering product in the customer order, associates it with the coupon deal, and automatically generates data defining at least one discount coupon for a product, typically other than the triggering product, based on the details of the coupon deal, which are not communicated to the customer prior to processing the customer order.

Abstract: A system for creating discount coupons in response to the purchases of products. Improvements disclosed include the printing of a "negative" coupon in response to the failure to purchase a particular product, and the printing of a coupon in response to the purchase of multiple triggering items, either without limitation as to the identification of the items, or with the requirement that the items fall into a predefined trade group. Other features of the invention permit the use of instantly redeemable "coupons," such that an instant discount is applied to a customer bill rather than having a coupon printed, and the logging, without printing, of possible coupon printings for statistical purposes.
