Abstract: Methods and systems for coordinating delivery of coupons issued by a network-based system are disclosed. For example, a system can include a coupon generation engine, a coupon widget, and a communications module. The coupon generation engine can issue a unique coupon redeemable exclusively by a registered user of the network-based system. The coupon widget can present the unique coupon via a first communication channel internal to the network-based system. The communications module can deliver the unique coupon to the registered user via a second communication channel external to the network-based system.

Abstract: A purchase record is accessed within a database of purchases. The purchase record includes a purchase date field and a purchase price field, respectively indicating a purchase date and a purchase price of a first item purchased from a seller by a purchaser. At a determination module located at a machine, a presentation delay interval is determined using the machine, the purchase date, and the purchase price. After expiration of the presentation delay interval, an advertisement is communicated to a device of the purchaser. The advertisement advertises a second item to replace the first item.
