I hadn't heard about this deal, so I'm glad I walked into Toys-R-Us to check out 3DS supplies. Best deal I have seen for 3DS games so far. Even after tax it beats Amazon's $10 credit with a 3DS game.
I'm now the proud owner of two games that should be very entertaining:
Unfortunately, my 3DS isn't due to arrive till Tuesday. But hey, saving $23 on the 3DS, and now $15 on two games is definitely a good thing in my book.
