Amazon offers the Armor All 88" x 17-Foot Commercial Polyester Garage Flooring in Charcoal Grey for $129.96 with free shipping. (Home Depot charges the same price.) That's tied with last week's mention and the lowest price we could find by $4, although most sellers charge over $150. It absorbs rain, melting snow, and other liquids, and features a PVC waterproof backing.
