Display models like tv would make sense. But electronics shops usually have boxed or packaged items so people don't get their grubby hands all over the items. In that image, none of the items on the shelves appear to be packaged at all, and the hand basket sorta implies that customers are to take items home with them as is.
It's more like a grocery store and shopping for melons.
If it was all just display models like say, a car dealership then you wouldn't have the shopping basket.
