I'm trading in NBA2k6 and Amped3 for Oblivian CE.
I don't know why everyone bashes the store, I bought NBA2k6 used for $45 at Blockbuster (which means in credit, about $20 cash).
I never played it (didn't really like) and had it on EBAY where it normally sells used around 30-35 dollars. Head about this deal, went to GameStop to confirm, and bought for a second game Amped 3 for $35-3.50 = $31.50.
So I'll play Amped 3 for a week, then trade it in for a $3.50 profit and get rid of the NBA2k6 at the same time for a guaranteed $35.00 It's actually more, because I won't need to pay tax on the Oblivian purchase, saving another $3.00 or so.
To summarize, I'll get Oblivian CE via this deal for about $54.00 out of pocket, plus have had NBA2k6 and Amped 3 to play for a while.
