Commodities are now available in the Diablo III real-money auction house. In an email to Kotaku (and on its official blog), Blizzard said as part of a patch released today that Diablo III's auction house will now let you buy and sell gems, dyes, crafting materials, blacksmithing plans and jeweller designs and training pages.
The patch will also fix various minor bugs.
"The ability to trade gold as a commodity is not yet available, but we hope to enable it in the near future," Blizzard said. [<a href="">Blizzard]
