I have had good luck selling on Craigslist. We sold a bed and my old bike on there. Didn't even have to come off on the price! Right now I have several formal dresses listed on there. No takers yet, but it isn't prom season.

That being said, I am leery of buying from there. I have been looking at trainers, but everyone has been real evasive about the details. How can you not tell me what year it is? Model? Argh!

My friend has great luck on there. He manages to find great things and talk the people down. It is almost annoying how good he is at it!
