Home Depot offers the Suncast Alpine Resin Storage Shed, model no. BMS7300D, for $499 with free shipping. That's tied with our expired mention from two days ago and the lowest total price we could find now by $115. It measures 103" x 43.5" x 90", and features transom windows, functional vents, 60" door width, and metal locks and hinges. Deal ends April 9.

Of note, it requires a foundation, which isn't included.
