Golly Blizzard, don’t sit on your hands or anything. Just days after promising and then enabling commodity trading on Diablo III’s auction house, the publisher has added gold trading to its offerings. So, yes, you can buy in-game cash with real money now. Since your mind has just been blown by legal and possibly even profitable gold farming, there’s room to put in some new things, like a warning that buying gold from any external service is strictly forbidden. Not to mention totally redundant.
