Thanks guys. I just bought it for $26.56. I had to put in my EDGE card 1st and then CAG16 2nd for both codes to work.
I had to do the same thing when I made an order a couple weeks ago. The used 360 game I bought online a couple weeks ago was Popcap Arcade Vol. 2 and it was labeled as defective when it arrived. I can tell it has rings around it and it is also scratched to hell. It also looks like someone took the sharp end of a nail and went to town on this disc for 10 minutes straight.
That being said, it's resurfaced and it actually works fine. Everysingle GS around me has Assassins Creed 2 used, so if it's in bad shape, I'm going to get it switched for a better looking one in person.
I haven't even played the first Assassin's Creed yet, but what the hell. Here's how I'm rationalizing it at 6:00am in the morning. I'm sitting on enough GS credit to waste a little bit. If I waited until the next B2G1, it would probably be around $34.99 used so 33% off plus 10% off would make it cost something like $20, give or take.
