A price verification method for retail stores using shelf pricing, and apparatus therefor, in which the shelf labels are provided with an extended bar code having the item number and price of the item. A remote unit scans the item number and price, and uses the item number to look up the item in a database which is identical to the store checkout scanner database, and compares the shelf price to the database price. If they are not the same, a new shelf label may be printed immediately. The method and apparatus described herein are easily adapted to allow government inspections of stores for shelf price accuracy. A further embodiment of the invention provides for a portable totalizer with which a shopper can total purchases as they are selected, enabling the shopper to check the scanner at the checkout register.
