Do you get the Dem Bones code from gamestop when you pick up Batman Arkham Asylum?

I preorderd The batman arkham asylum collectors edition, and i wanted to know if the give you the code for dem bones when you pick the game up, or when you preorder. I preordered long before dem bones was announced, so i just want to make sure.Do you get the Dem Bones code from gamestop when you pick up Batman Arkham Asylum?
It would be best to contact your local Gamestop to find out. Let them know that you preordered it before the Dem Bones map was announced and ask if you pick it up when you get the game or when you preorder.
