Just a thought out loud: The Walmart Arcade + $100 gift card should mention the fact that Amazon matched the deal (which I took advantage of). That deal working for anyone with net access made adding another 360 to the household an impulse purchase.
Edit: Of course I just re-read the part where this is a 'brick & mortar' sale. Oh well, I guess WalMart caused the $100 card, so they can keep my vote. Amazon just got my money!
