A price change verification system and method for an electronic price label (EPL) system which verifies that price changes have been implemented by associated EPLs (22). A storage medium (26) contains a record associated with the EPL. The record includes a price change time and a new price for the EPL. An EPL computer (24) sends a price change message containing the new price to the EPL at a time substantially equal to the price change time. The EPL computer additionally verifies that the EPL is displaying the new price by reading the record to determine the price change time, obtaining a currently displayed price from the EPL, and comparing the currently displayed price to the new price.
