Preorder Mario Kart 8, get free fuel. Real fuel.
Best Buy is running a promotion for Nintendo's cart racer, offering a $10 prepaid MasterCard for those who put in orders for the game now. Though the premium is a $10 card usable anywhere MasterCard is accepted, for fuel or anything else, the sales pitch is that you get free gasoline if you go ahead and commit to the Wii U game.
Pre-orderers have to register a code by June 30 to collect the goodie. Mario Kart 8 launches on May 29.
