Techniques for informing customers of impending price changes of items in a retail establishment are described. An EPL computer reads an EPL data file to determine when an upcoming price change for an item is scheduled to occur. The EPL computer transmits a timer countdown message to a EPL associated with the item which includes a time remaining until a current price is to be updated with a new price. The EPL then displays the time remaining for the current price, providing valuable information to customers who are in the process of making purchasing decisions. In one aspect, as time passes, the EPL computer sends further timer countdown messages to the EPL containing updates of the time remaining, allow the EPL to display the updated time. In another aspect, no further timer countdown messages are sent to the EPL, as the EPL includes EPL circuitry which decrements and updates the time remaining as time passes.
