I also can’t seem to purchase through Guild Wars 2, but I havent submitted a support ticket.
I live in Canada (Westcoast), not quite sure if this has anything to do with it
I’ve tried paypal and visa and neither works
I’ve been trying to purchase Guild Wars 2 since two days ago, however my credit card and my paypal was denied, so i decided to buy through a third party (dlgamer), so its not just the gem shop, I couldnt even buy the game via whatever Arenanet has set up
