I was at Walmart today and saw ads for a MW3 tournament on Nov 7th. I guess more than 2,700 Walmart stores will host tournaments starting at 8 p.m. on November 7th where gamers get early hands-on time with Call of Duty: Modern Warfare 3 before the game goes on sale at midnight. Winner will get a free copy of the game.
You may want to check with your local Walmart and see if they are one of the participating stores.
