Home Depot offers the Gladiator 4-Shelf Steel Shelving Unit, model no. GARS774SZG, for $139.30. Opt for in-store pickup to avoid the $55 shipping charge. That's tied with our mention from two weeks ago and $61 below what you'd pay at your local Lowe's. It measures 77" x 73" x 24" and supports 2,000 lbs. per shelf.
