Coupon information is provided electronically in association with receipts for transactions at physical stores and/or online stores. A retailer causes performance of a transaction in which one or more items are purchased. An interface configured to accept input indicating a customer identifier, such as an email address, associated with the transaction is provided. When input has been received via the interface, it is determined whether the identifier is associated with a known customer identity. If the customer identifier is associated with a known identity, digital coupons associated with that identity are applied against the transaction. An electronic receipt is further provided for the transaction via, for instance, the provided email address or a web-based application in which a session is established in connection with the identity.
