  • Publication number: 20010023407
    Abstract: A method and system for distributing promotional offers and other incentives to consumers over a communication network and for the consumers subsequently to redeem at least some of the offers is disclosed. The invention includes storing manufacturers offers and/or retail incentives in a database C associated with a co-operative communication network site 2 and providing information from the database to a consumer in a response to a request from a consumer to the database. The consumer may be connected directly to the database or may be given access to the database while logged into a retailer's or manufacturer's network site in such a way that the consumer is not aware that information is coming from the co-operative communication site. In addition, a transactional second database D is provided for recording transactions on the first database C so that when a consumer selects offers, step 27, from the database, an order is generated, step 28, on the transactional database.
