Abstract: A coupon distributor receives, from coupon provider(s), data describing coupon offer(s). The coupon distributor operates a server that causes approved source(s) to generate coupons for the offer(s). The server receives, over a network, from a retailer, coupon redemption data indicating that the retailer accepted a particular coupon. In response, the server determines whether the particular coupon was generated by an approved source and that the particular coupon was accepted in a manner consistent with the offer amount and terms. The server further determines whether the server has previously caused any retailer to be compensated for accepting the particular coupon. In response to positive determinations, the server marks the particular coupon as redeemed and further causes the retailer to be credited for the particular coupon. In an embodiment, a retail server causes a digital coupon to be generated for an offer during the same transaction in which the coupon is used.
