Costco is having a sale on their MotoFloor Modular garage floor tiles starting now until May 31st. For a pack of 48 tiles, it is $99.99 which comes out to $2.08/sq-ft. MotoFloor is made by the same company that makes RaceDeck, i.e., SnapLock Inc. They are high quality products made in the USA. 10 year warranty. Shipping is included, but you'll probably have to pay tax since Costco operates in almost every state.
Color choices include: black/white, black/alloy, charcoal
Completer kits also available for the edges.
Note: the other Craftsman deal i posted is a slightly better deal per sq-ft (http://slickdeals.net/f/4299086-Craftsman-polypropylene-garage-floor-tiles-1-85-sq-ft-74-19-for-pack-of-40-Sears?v=1&t=4299086
), but I haven't figured out who manufactures those floor tiles. Where as, I'm certain MotoFloor for Costco is made by SnapLock.
