Who says registering Nintendo products doesn’t earn you anything?  Nintendo has unveiled its July goodies that you can buy using the virtual coins you earn from registering said products, and they’re actually not bad.

For Wii owners, you can snag the N64 classic Mario Tennis – which is an ultimate multiplayer classic – for a meager 150 coins.  This game is yours to keep, and a lot of fun if you love the sport of tennis.

If 3DS is more your speed, you’ll be able to download the musical mini game Electroplankton Rec-Rec for 100 coins.  Remember, this is just one small activity from the full game.  But for that small a price, it’s hard to beat.

Rec-Rec is available through the 15th, while Mario Tennis can be had all the way through July 22nd.  We suggest picking up on both of these games sooner rather than later.

Also, a side note – Nintendo has revamped its coin system so that the values on surveys are a llttle less, while the values on game codes that you redeem are actually worth more.  So buy more games!
