A few years ago someone gave me Resistance 2 and I brought it back to Best Buy with no receipt and got $60 (plus tax) in store credit. I had no idea if it was actually from Best Buy. I suppose that was a few years ago, maybe they've all cracked down on such practices now. The morally corrupt (thieves) are ruining it for the morally grey (retail exploiters/me).
In the end though, I will one day own a Wii U and I will want to play this game. I'm gonna keep it. Although, Oblivion, there's a good chance I could get my hands on a second Old Navy copy of NSMBU from my sister's friend that she went with last night. If that happens I'll hook you up.
