The Auction House is a feature of the PC version of Diablo III. This allows players to put items up for auction, bid and buyout. Two versions of the auction house exist. One uses gold earned in-game while the second uses real-world currency. Sales and purchases from the Real Money Auction House (RMAH) can be funded by either the players Battle.net account balance or a separate e-commerce service such as PayPal.
The auction house will be discontinued on March 18, 2014. Blizzard's original goal was to provide a convenient and secure system for trades, but it was found that the auction house undermined the game's loot-based gameplay. Subsequently, Loot 2.0 will be introduced in Reaper of Souls.
