Actually you can load as much time as you want on the rankupxp account, however you can only apply 24 hours maximum to one gamer tag or psn ID. Basically I forgot about the combat cards giving xp and added one too many codes, but you can always give the extra hour to a friend.
No, Paypal only.
EDIT: 25 hour account has been sold! Working on getting another account to 24 hours, if anyone is interested let me know.
I have been selling these accounts on eBay but I guess eBay is cracking down so I thought I'd try here.
I have 1 rankupxp.com account for sale that has 25 hours of double...
