From OP's following post, it is clear that someone called "jercos" sold him the "World's Most Expensive Pizza"
But when I searched the forum for the member "jercos", there seems to be no one with that username.
When the forums changed to the current forum software, some old & abandoned usernames ceased to exist. You can't find my old username either, and that's a good thing, because I was unwise enough to use my real name.
