A price maintenance system and method in which price information entered into or read from a price-lookup file is shared to avoid price mismatch. The price-lookup file and price changes to the price-lookup file are shared by a point-of-service system including a bar code scanner, and a routine for printing labels. The system includes a computer coupled to the point-of-service system which updates the prices within the price-lookup file and sends the updated prices to the label printing routine for printing by a printing system. An electronic shelf label system may also share the price-lookup file and price changes to the price-lookup file.
