<p>To avoid the time and cost of manually changing price labels for each product column on each shelf 104, 114 within a vending machine 101, 111, a single elongate price display 206 is provided having an electronic price display region 205 for each product column on the shelf and a single set of electrical connections to the controller 301. Price values for each product column are stored in a memory 302 accessible to the controller and may be quickly and easily changed using an external device, such as a hand held data carrier with a DEXUCS interface or a wireless device. Small price changes may thus be economically effected.</p> |
