If you want a just couple of shelves, they are not be the cheapest as the shipping cost is high due to freight minimums, and their shelving is too heavy for UPS. But that is a good thing, it is heavy and heavy duty high quality. And if you want 4 or 10 or 100 units, this is definitely the best place to buy rack and shelving. Their prices and product knowledge mean that you get a really good deal, with well thought out shelving design at better prices than anywhere else we tried.
