This 48" x 24" x 72" Steel Shelf Unit lists for $109, but we found it discounted to $65 at Walmart. It ships for free, but you can also choose to pick it up from select stores at no extra charge. Because of these free shipping options, it's the best deal we found anywhere online. The unit's fives shelves hold a maximum of 4,000 pounds of weight. Sales tax is charged in most states.
