FYI on HALO: CE - Purchased this a while back during a similar Gamefly deal. It came in scratched to hell. I called a CSR for a replacement and she said the deal was over so all I could get was a refund. No biggie. I asked if I could get a $5 credit so I could return and re-purchase at the sale price. Her supervisor agreed. Bonus.
Second disc came and was also unreadable. So as not to

with the nice CSRs any further, I traded in my copy to another store that does 100% trade-in cedit and purchased a readable copy. (kind of dickish to other used buyers...but oh well)
TL

R - Had two Gamefly copies of HALO: CE and both wouldn't read. Hope that helps someone make their decision.
*edit* My experience with Gamefly is 50/50 and I still jump on these deals. I just don't jump on the titles I think might have a heavy in/out rate. Kind of like dating, eh
