Mario Kart 7 was an absolute blast on 3DS, and (in my humble opinion) one of the best entries in Nintendo’s popular racing franchise. If you never got around to playing this handheld hit, you can pick it up on the cheap side now. Nintendo is currently selling the game for just $16.50 through its official Amazon store. The deal is for a digital copy of the game, so you pay the cash in exchange for a code that lets you download the game on your Nintendo 3DS.
