Delivering promotions associated with user profiles through multiple digital channels associated with the user profiles

Multiple copies of the same coupon are delivered to a consumer simultaneously via different delivery channels. After one copy of the coupon has been presented in connection with a transaction and used, the coupon is marked as used with respect to all delivery channels for that consumer. Different copies of the coupon can have different coupon identifiers, for example when delivered through different channels. Consumers also can access such multichannel coupons without having to login each time they wish to access their coupons from multiple channels. In one implementation, each consumer has a user profile. A promotion is associated with that consumer's user profile. Each user profile also is associated with different channel identifiers representing communication channels to deliver instances of the promotion to the consumer. Each delivered instance of the promotion includes a coupon identifier associated with the promotion.
