PROBLEM TO BE SOLVED: To make changeable the transaction condition according to the stock condition by determining and displaying the second price of an item on the basis of a second threshold stock parameter when first and second threshold stock parameters are different. SOLUTION: A transaction managing software reads out a transaction managing data file, selects a category of an item to be investigated and confirms respective items and current stock levels (S62 and S64). The levels of items in the category are summed up, the current level of that category is acquired and compared with a threshold level in the transaction managing data file and when the current category level has the current price and other conditions within the same category level in the transaction managing data file, the operation of S62 is continued (S66 and S68). When they are out of the width, the transaction managing software changes the conditions such as price in a PLU data file and displays the new price and conditions corresponding to the level width in the transaction managing data file to an EPL software (S70). |
