I'm amazed no one posted this yet but Code Name Steam for the 3DS is only $12.99 at EBGames. It released this March to good critical reception. A must buy if you can find a copy like i did today.
You can easily price match this with Best Buy for an extra 10% off. I'm also surprised this went to $13 so fast for a Nintendo game. I'm guessing it wasn't selling that great, so EB decided to cut their loses.
I would price match this before other retailers follow suit and lower it.
