Publication number: 20120246033Abstract: The invention relates to a method and a system for converting an online interaction into a brick-and-mortar or online transaction between an Internet user and a plurality of merchants via the Internet. This invention assesses a buyer's purchasing intent and provides offers based on the buyer's purchasing intent and the buyer's purchasing score. The method involves maintaining a database of buyer attributes and receiving from a buyer a request for one or more offers. After receiving a request, a special intent server determines a purchasing score of the buyer based, at least in part, on information stored in the database of buyer attributes. Next, after a purchasing score is determined, the request and the purchasing score are transmitted to one or more offer sources. Finally, the intent server and the method then receives one or more offers from the offer sources and provides them to the buyer via the Internet.Type: ApplicationFiled: March 25, 2011Publication date: September 27, 2012Applicant: Per Choice, Inc.Inventor: Bruce Keiser
