Abstract: A price verifier employing customer-specific information to allow for the display of prices adjusted for membership in frequent-shopper programs or other programs which offer prices adjusted according to the identity of a customer. A customer enters a product identification, for example, by scanning a barcode label. The customer is then prompted to enter customer identification information, which may be done, for example, by scanning a frequent shopper card. The price verifier looks up the product price in a price lookup table and then looks up price adjustments based on the customer identification information. The price verifier then displays the adjusted price. The price verifier may also advise the customer of promotions associated with the product being verified, or related products, and may also inform the customer of promotions associated with promotional or frequent shopper programs of which the customer is a member.
