I am selling gold on horde area 52 US server for a very cheap price 50 USD per 200k I have 450k gold available at the moment but I will only sell via playerauctions. If youre interested go to look on area 52 horde US and buy from the seller CM_Reaver (that's me). This site takes out all of the risks of buying and selling gold and thats the reason it is the only platform I will use to sell my gold.
EDIT: My stock has been mostly bought out but keep an eye out on player auctions as I will be stocking up frequently and this is where I will be selling my gold always!
