The unit has two digital displays (4,7) of different sizes arranged in an elongated rectangular housing (3) and showing the normal and "special offer" prices. The displays are arranged with a flashing arrow (8) operated by electronic control to draw a potential purchasers attention to the lower price. The meanings of the two prices are distinguished by inserts (5) into upper and lower compartments (9). A transparent cover (11) can be slid (6) towards the other end for access to these, but protects the price displays themselves at all times. |
