In the January promotion (in the UK) you received a code for a free game (art academy, Mario Land, Layton etc.) and you could redeem as many as you had. I bought Mario and Layton codes off a forum and both worked. Anyone know if the current 'so many games' promotion is the same or are they linked to your account somehow? I ask as I am looking to trade my physical carts for download codes of the same games but don't want to end up with a bunch of codes I cannot redeem and no carts...plus I will qualify for a free game code myself. Anyone gone through this and received a code not linked to their account (and someone else has used it) or redeemed more than one?
