Probably more than I want to think about. I haven’t really kept track but It’s been at least $10 a month minimum since I started. I would probably peg it at around 350-400…with the months I’ve gone crazy overboard with items I’ve just had to have. And converting it into gold has been a serious addictive lazy out when I get bored farming for items. (But to be honest I get more gold for my time buying it than I do earning it. : /)
