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.
