TRU B2G1 or FYE 2 for 1?

I wanted to get everyone's opinion on something. I have access to a few cheap 360 games, $20 a piece. My FYE says it takes any 360 game for the 2 for 1 deal. I was debating which of the deals, TRU or FYE to capitalize on. I could trade in 4 360 games at $80 cost to myself, and get F.E.A.R and I guess Marvel Ultimate Alliance (I'm iffy on it.) from FYE via their promotion. Or I could spend more money and get Enchanted Arms, Chromehounds and Marvel Ultimate Alliance at TRU for like $125 and then go back and exchange Chromehounds and Enchanted Arms for Call of Duty 3 and F.E.A.R once they are re-leased. They come out within the 30 day exchange period. Worst case scenario is that I just return all the games anyway if they don't let me exchange. This isn't a good time for me to spending alot with the new consoles coming soon but its hard to pass up 2 or 3 games for like $40 a piece.

Get even cheaper than 20 games(Madden 06 15 preowned) and do the FYE deal imo

The trouble with the FYI deal is that I probably can't squeeze Call of Duty 3 out of it since it ends before the release date. I also imagine that since its a "trade", they don't let you exchange it so there is no loophole to exploit. The only game worth it would probably be F.E.A.R. then, my FYI doesn't seem to stock much of anything.

You can return sealed games with or without a receipt for credit at FYE. Return policy is even clearly labeled by most of the registers for you to read (and/or point out to clueless employees).

I returned Hitman: Bloodmoney for Lego SW2 and Onimusha 4 for store credit last month.
