Amazon offers the Suncast 7.8x7.9-Foot Outdoor Storage Shed, model no. GS9000A, for $554 with free shipping. That's the lowest total price we could find by $45, although in October we saw a similar shed for $4 less. It features 311 cubic feet of storage, a 62" x 69.5" door opening, resin floor, and lockable doors.
