Say Goodbye to Diablo III's Auction House
There were a lot of reasons to dislike Diablo III at launch, but one of the major ones is finally gone – the auction house. With Diablo III's first expansion pack, Reaper of Souls, arriving March 25, Blizzard decided to remove the gold and real-money auction houses a week in advance. Players have until June 24, 2014 to claim all gold and items from the Completed tab in both auction houses before the auction house window goes away for good.
