<p>A method of assigning electronic price labels (EPLs) to groups of price look-up file items which is based upon the price change frequencies of the items in the groups. The items are divided into a plurality of groups. Price change frequencies for items within each group are determined. A minimum price change frequency for each group is determined. In a first embodiment, EPLs are assigned to items in any one of the groups only if a predetermined number of the price change frequencies in the one group exceed a predetermined minimum price change frequency for the one group. In a second embodiment, the groups are ranked starting with a first group having a highest number of items that exceed the minimum price change frequency for the first group and ending with a second group having a lowest number of items that exceed the minimum price change frequency for the second group, and EPLs are assigned to a plurality of items less than the totality of items by order of rank of the groups, beginning with the items in the first group, until the plurality of EPLs are exhausted. <IMAGE></p> |
