I just noticed that this game dropped at gamestop to 39.99 and 34.99 (new & used), which made me wonder if there were any places that had dropped their price as well, hopefully lower.
Looks like there are only three xbox 360 available for purchase from gamefly right now. You can choose to keep it for 21.99, but I'm no longer a member.
If I could find it for 14.99 I would jump all over it!
