9 days before release of a major game, GAME/Gamestation have lost the ability to supply EA games [what the cluck they did to get this revoked, I have no idea, but it must have been huge].
So, if you've pre-ordered or have a DH/DCs who have- particularly the Collector's Edition (which I did for a birthday present) of Mass Effect 3 - you need to get Zaavi and reorder it (as is the instructions for EA itself though Amazon doesn't seem to have the Collectors version).
