A Graphical User Interface (GUI) is provided to change prices at the store(s). Prices may be changed for a single store, or a Store Group. Buy-Downs may also be changed using this interface. Products can be presented for editing by name, UPC Code, or partial UPC codes to select by manufacturers. Prices may also be included in the search. Example - All Marl% products with a price of $3.26. the “%” sign is used for a wild-card, and changes made across an array of products. (See below). Price changes are immediately transmitted to the POS system. Price changes can be made using any device that can use AS/400 client access from any location where an Internet connection is available. For instance, you can change prices using your laptop from a airport terminal, office, or hotel room. A profit percentage alerts you if the price change is in line with the company’s profit margins.
