The system (1) includes a programmable computer (16) operatively coupled to communication link (14). Each data item includes geometrically descriptive terms and trading parameters identifying characteristics of an item offered for sale by an advertiser (10). A profile is generated by a user which includes identifying characteristics of an item sought for purchase by the user. The profile identified by the user is compared to each data item stored in the data base (18) and data items are identified which match the profile.
