Home Depot offers the Gladiator 77" 4-Shelf Steel Garage Shelving Unit for $139.99 with free shipping. That's $10 under our mention from February and the lowest price we've seen. (It's also at least $40 less than you'd pay at another local retail store.) It features a welded steel frame that can support up to 2,000 lbs. per shelf. Deal ends July 5.
