I couldn't find a topic that had this, and thought it would be an interesting discussion.
I was mostly curious on how much some people have made on a single item selling it on Steam, and what item that was. But feel free to post any sort of marketplace selling statistics.
I think my top sale happened just like week (and was top by a large margin) when I sold an Asimov P90 for $56, after paying 2.79 or whatever for a key.
What about you?
