A subscription system allows a customer to establish a subscription to a
product with one or more retailers (e.g., by establishing the
subscription through a controller or central system). In one embodiment,
a subscription is established by receiving a request to establish a
subscription and receiving information that identifies a product. Terms
of a subscription for the product are established. The established
subscription is identified by a redemption identifier which is
communicated to the customer. It is also determined whether the customer
is complying with a frequency of the subscription.
