I have a game fully paid for at Rhino/GS from the trade 2/get 1 sale a while back, but I dont want the game. I want to move my credit over to Super Paper Mario instead. My question is, can I just wait until SPM comes out before A) moving the credit over to SPM, or B) Just get the original game, then return it for SPM. Either way, should I do anything about it now or just wait a couple weeks? (the game I had preorderd came out yesterday)
