Honestly, I think it'd be easier for you if you just buy the whole deal and sell off your copy without the box. There are so many copies out there floating around without the box (to the point where copies without the box are being sold as "complete" on eBay, and I'm not talking the GH version either). But since the game is really cheap, you should be able to get a boxed copy for no more than, say, 20 bucks.
