Walmart offers the Better Life Technology G-Floor RaceDay 12" x 12" Diamond Tread Garage Floor Tile 20-Pack in Midnight Black, model no. T95DT12MB20P3, for $46.79 with free shipping. (It's available in Absolute White for a few cents more.) That's the lowest total price we could find today by $13, although we saw it for a buck less in February. These polyvinyl tiles feature peel-and-stick backs for easy installation.
