Abstract
This guide has been developed to provide retailers with information about the best practice requirements for the unit pricing of pre-packaged commodities. The guide consists of best practice recommendations that will improve the accuracy and usability of unit pricing information offered in retail stores. In addition, the guide will help provide uniformity across all states and types of stores.
