so, the pre-order process has started and everyone is rushing to get their pre-order in. Pre-ordering at gamestop gets you the free expansion pack along with beta access.

However, wal-mart is throwing us another bone. Although they are not offering early beta access, you still get the expansion pack along with a FREE copy of BF3, so for those who pre-ordered MOH:WF, this might just be the deal for you
