Have you checked out FaceBook's MarketPlace? I have placed a few items on sale there and though I never had any buyers, perhaps other sellers had different experiences. This is a very social perspective on selling since the ad appears on the threads of friends' updates.

I forgot to add Etsy - http://www.etsy.com/
It is a site to buy and sell handmade stuff. Very interesting concept.

there are great list
but what i need is not list but the practical experience
if u can share it would be great
