This deal probably works great in small markets where there aren't many SDers and lots of people that use CL.
Large markets are tough... so many flaky people that are really interested and then just drop off the map.
Not true at all. I live in a "small market" and all I get are lowball offers. I am guaranteed to get offers of around 33% of my asking price. I don't mind hagglers; I price accordingly to adjust for that- but people are ridiculous. If I have a brand new Ipad I'll definitely get "will you take $150?" or even better "will you take $100 and my 15" CRT monitor?"
