User blog:SpetSnAZ CM/(Please Help) Black Ops shipping

So i preordered Black Ops from gamestop and it is not availiable for in store pickup. It has to ship to me. Will the game make it to my mailbox the day it comes out or will i have to wait an extra day(s)? If it doesnt make it to my mailbox tuesday, can i change my method to in store pickup? If so, how?
