I bet you guys are wondering why haven't I got the game yet. Well I've been busy with shcool and have no time for games. But since finals are over I'm trying to find a cheap call of duty 4 around 40-45$.
I think your best bet is to use this coupon (got it from SD). A lot of places had it on sale for 39.99, in fact i think about 2 days ago amazon had the 360 version for 39.99 as their deal of the day. The deal seems to come back from time to time, I'm thinking it may go on sale again just don't know when.
