A system includes a transaction handler, a data warehouse storing data associating offers and consumer accounts, a transaction handler coupled with the data warehouse, and a transaction terminal configured to submit authorization requests to the transaction handler via an acquirer processor. After receiving account information identifying a consumer account for a payment transaction, the transaction terminal generates a first authorization request identifying the consumer account. The transaction handler identifies offer information relevant to the payment transaction and provides an authorization response containing the offer information, prior to communication with an issuer processor for the payment transaction. In response to the offer information provided in the authorization response, the transaction terminal modifies the first authorization request to generate a second authorization request, in response to which the transaction handler communicates with the issuer processor for the payment transaction.
