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.
