Not really Justg. To buy plat i need an valid and active account on the US apple store, since the $ will debt from the credit card registered on the apple store account. There's a kind of account, that is registered using no credit cards, (like the redeem codes, etc...). Since many worldwide players that don't live on US, have this type of account, we cannot buy the coins to upgrade our characters/accounts.
=(
That's just sad. /sob
lol

EDIT: GEEZ. My english SUCK a lot.. rofl
