摘要：
A method of assigning a promotional message to an electronic price label (EPL) which uses a promotional indicator in a price file to access a promotional message in a promotional message data file. The method includes the steps of storing promotional messages and associated promotional indicators in a promotional data file, storing one of the promotional indicators in an item record within a price file, reading the price file to obtain the one promotional indicator, comparing the one promotional indicator with the promotional indicators in the promotional data file to obtain a promotional message that is associated with the one promotional indicator, and causing the EPL to display the promotional message.
