发明名称 Methods for e-coupon extension
摘要 A method for redeeming e-coupons beyond their expiration. The method comprises: maintaining an e-coupon database that comprises an e-coupon identifier, an e-coupon expiration condition such as an expiration date, and a post-expiration instruction; receiving a request to redeem the e-coupon associated with the e-coupon identifier when the e-coupon is expired; and executing the post-expiration instruction associated with the e-coupon identifier. Preferably, the request to redeem an e-coupon is received from a consumer using a graphical user interface. A preferred post-expiration instruction is selected from the group consisting of rejecting the e-coupon, fully redeeming the e-coupon, partially redeeming the e-coupon, issuing an alternative e-coupon for the same product or a substitute product, and combinations thereof.
