I don't see the point of posting this on a forum. Nobody would use the mailing system unless the two people actually knew each other. And if some was actually interested in selling it they would look on the trading post. You do know there isn't an order fee right?
This actually sounds like a pretty good deal. I'm VERY interested. My in game is same as here, just mail me the item and then I will send you the gold. Mail the item first though so I know it's not a scam. You can obviously trust me because I'm some guy on the internet and they can't put anything on there that isn't true.
