With the launch woes surrounding Diablo III behind it, Blizzard has announced that the real Money auction house is now available for the game. This is where you can go to sell the things you find in the game for real money. The auction house is available for the Americas region in US dollars, Australian dollars, and Mexican pesos.
Other areas of the Americas and Europe will launch later. The real money auction house is accessed by clicking on auction house button on the left side of the campaign screen and in choosing your country's currency. Items can be purchased using PayPal or Battle.net Balance.
