PROBLEM TO BE SOLVED: To confirm the transmission of sales price change to an electronic price tag device. SOLUTION: In this system, the designation of designated price change for an electronic price tag(EPL) related with a sales item is confirmed, and this system includes a storage medium for storing an EPL data file and a spool file and a computer. The computer executes a designated price confirmation program. In this case, the program reads the EPL data file for obtaining the identification information of an item related with the EPL, reads a price file for obtaining a new price and a time for validating this, and reads the spool file after the time for judging whether or not the recording of price change for the new price is included. When the recording of the price change for the new price is not included in the spool file, a price change message including the new price is designated. |
