Amazon is selling crackdown for $39.99
If you want to buy the crackdown for Halo 3 MP beta, it's the time.
otherwise, just wait because it will be really cheap after beta ends...
I just gonna trade-in my Xbox to EB.
"Get a Microsoft Xbox 360 System Pro for $319.99 or a Microsoft Xbox 360 Core for $219.99 with trade on an Xbox System"
i think that is pretty good deal for me.
