That is the one downfall about Craigslist. There is no "contract" like there is on Ebay. It's like a game of chance. I had set up an appointment to pick up a scenes and settings for $25. At the last minute they emailed me and cancelled. Saying she had done her research and was underselling herself. On the other hand, I have picked up two great deals off Craigslist because they just wanted the stuff out and didn't care what the real value was! So, yes you have a right to be upset, but don't worry, a better deal will come your way!
