You know the ones I am talking about...the big gigantic flat ones that are too wide to fit on the shelf or wheel well. They wind up lying in the middle of floor and you keep tripping on them, stepping over them and working around them. What I do is to stand them upright against a shelf (preferaby the one they are PAL'd to, but any one will work) and then use bungee cords to "tie" them tightly to that shelf so that they remain upright, secure and out of my way until I deliver them. The hooks on the bungee cords will fit right over the lip of the shelf and stay attached as long as they are tight enough. Its a simple little trick that can really make the day go easier.
