A display device for mounting on the vertical front wall part of a nestable type shopping cart, the display device having a pair of display panels carrying intelligence mounted on opposite faces of said front wall part for vertical sliding travel between a lowered retracted position and an upper extended display position. Biasing means normally maintain the device in extended display position. When a shopping cart is nested into a second like shopping cart, the upwardly swingable rear wall part of the second cart is engaged by camming structure on at least one display panel to swing said rear wall part upwardly and thereby apply downwardly directed force against said display device to vertically slide it to retracted position.
