I have done this 2-3 times, but I haven't recently... 1. Go purchase a Microsoft points card at the store (not online). 2. Go home, tear off the little tab, and very carefully write down the 25 digit code. Do NOT enter the on your xbox live account. 3. Go back to the same store you purchased the card from (preferably in a timely manner). 4. Tell them that the code didn't work and that, and they should make some phone calls, verify that the code wasn't entered, then give you another code. 5. Now you have twice the Microsoft points for the price of one.:thumbup: I didn't see any other threads like this so I thought I would make one! Press "thanks" if this helps!
