Great variety of choice when it comes to buying in game gold. But paypal doesn't work! Apparently to do with their risk management. What's worse is that they don't tell you why. If it doesn't work altogether, then why put Paypal as an option.
If you don't have a credit card/bank account then the only other ways are to use bitcoin or skrill which are usually more costly than paypal.
Big disappointment, would have to look for other options
