Have you already pre-ordered a 3DS from Amazon? You just made $25. Well, you've still spent $250, of course, but you'll get $25 back in the form of credit. Likely in response to Kmart's $25 credit offer, Amazon is including a $25 credit with 3DS pre-orders, which can be redeemed toward a selection of 3DS games.

In addition, that same selection of 3DS software comes with a $10 credit toward a second 3DS game. We would be very surprised if the credits stacked, so don't expect an aggregate $35 bonus on your 3DS and game order. But in any case, money is saved!
