I sell 3 hours for $15. I have sold many and have tons of positive feedback on ebay @ grandmas_sweets. I deliver within 10 minutes. My email is [email protected]. All I need is the money, the gamertag and the system you play on.

How does the double exp work? Is it 4 hours in-game time? How do you apply the codes?
