My guess is that there was no one with 200 bucks coming- he just said that to try to get you to pony up... The old bait and switch!
I've been screwed over like that before. I never have come up with the right words to say when it happens, I just leave. Then, usually on the ride home, I think of the right words to say- like, "You know, people that make an offer like you did, and get people like me to drive three hours on your word, and then you go back on your word- those people sometimes find that their house burns down!" hahahahaha
Of course, you do know where he lives now. You could take a dump in a box, and mail it to him.. Although- that might be illegal..
