The only thing I can think of is to see if you can find it used? Or maybe some where like Amazon? Be careful though EA has been cracking down on used game codes. They lock it to where you can't use it. So if you're lucky to find a copy, hopefully it's new or used, but not registered. -- Already registered game codes may not be able to be used to install the game.
I've read conflicting issues with the game codes.
-- You can still install and play the game, it's just you can't register the code with EA/Origin and therefore can't use it with store stuff and whatnot.
-- You can't install and play because the game code has been locked by EA/Origin.
