摘要

A computer based system is provided for sales of a product or service. A gateway system is provided that has a database with one or more catalogs of content for products or services: A merchant interface, for a merchant, is coupled to the gateway system. A buyer interface, for a buyer, is coupled to the merchant interface and the gateway system. The gateway system hosts the purchase of products or services by a buyer in a manner such that purchase of products or services, by the buyer, appears as a purchase through the merchant interface and not through the gateway system.
