Walmart offers the Edsal 48" 5-Shelf Steel Shelving Unit in Black, model no. UR245L-BLK, for $50.87 with free shipping. That's the lowest total price we could find by $9, although we saw it for $2 less on Black Friday. It measures 48" x 24" x 72" and features adjustable shelves and a 4,000-lb. total capacity.
