Do not buy from there. I waited more than 48 hours for my gold which i did not even get in the end. The support seems mentally $#*!ed and is always answering only half of your questions with an IQ of a stone. The money back promise is fake and i had to get my money back via my bank.
Safe your money and buy your gold at the right time via the WoW Auction House Coin.
Have a nice day
