Unfortunately, this coupon is nowhere near as good as last month's Nintendo Zone coupon, but I am posting this up for the sake of it.
Bring your 3DS to a Best Buy 3DS kiosk and connect to Nintendo Zone to retrieve the coupon. Or you can get it from a Starbuck's wireless hotspot like I did. Coupon expires 4/8/2012.
There is a much better B1G1 50% off deal at TRU currently going as of the creation of this topic: http://www.cheapassgamer.com/forums/showthread.php?t=316773
