One or more items of interest are obtained from a user. The physical location of the user is determined. A query based on the items of interest and the physical location of the user is then created. A network of information is queried utilizing this query. A customized offer is received from a retailer-based agent in response to the query. The customized offer information associated with the items of interest and their locations relative to the physical location of the user is displayed.
