A computer-implemented method for generating coupons is provided. The method comprises receiving a request for a coupon from a publisher; responsive to the request selectively generating a coupon, said coupon comprising: (a) a unique coupon id; (b) code associated with a clipping button which when executed on a customer device configured to display the coupon together with media content and an ad unit associated with the media content, causes the customer device to send a clipping notification message including the coupon id to the coupon server system upon selection of the clipping button by a customer; sending the coupon to the publisher for displaying with said media content on the customer device; receiving the coupon clipping notification message from the customer device upon selection of the clipping button by the customer; and creating an association between the coupon id in the coupon clipping notification and the customer.
