ABSTRACT:
A system and method of determining price differences between price files which minimizes the possibility that an incorrect price is displayed by an electronic price label (EPL). The system includes a computer which reads the first and second price files, compares the prices for the items in the first and second files, and identifies predetermined items having different prices in the first and second files. The computer is preferably an EPL computer. Once a price discrepancy is identified, it may be logged and acted upon in accordance with rules established by an operator.
