Walmart offers the Edsal 48" x 18" x 72" 5-Shelf Steel Shelving Unit, model no. UR1848P-BLK, for $49. Pad your order over $50 to bag free shipping; otherwise, shipping adds $5.97. (You can also opt for in-store pickup.) That's tied with our mention from last week as the lowest total price we've seen. (It's the best deal now by $6.) It features adjustable shelves and a 4,000-lb. weight capacity.
