Global Gameflip issues

Some countries dont normally have a zip code/postal code, the place i live in(hong kong), does not. Will this problem affect my purchases in gameflip due to it requiring a postal code or zip code?

Are you receiving any error messages while trying to complete a purchase? As of right now we do only allow Hong Kong to use PayPal as payment and we pull the address directly from your PayPal account to complete the transaction.
