Methods (74, 76, 78) utilizing a network (20) of computing systems (22) facilitate execution of a transaction (114) between a consumer (38) and a provider (32). Preference data (108) defined by the consumer (38) is stored (76) in a database (82). When a request for the transaction (114) is detected at a transaction site (46), a consumer identifier (104) for the consumer (38) is utilized at the transaction site (46) to retrieve (220) the preference data (108) from the database (82). The preference data (108) identifies one or more products (96) offered by the provider (32) and preferred by the consumer (38). The transaction is performed (232) at the transaction site (46) to provide the product (96) to the consumer (38) in response to the retrieved preference data (108).
