Flippa is useless and Lot of cheating happens. I am a victim of it. Will write a blog on it later. But stay away from it. IMO, warrior Forum and DP Forum are best places for buying/selling.
I haven't actually bought anything or sold anything there. But I check it once in a while to see how fast people have developed profitable websites, in which niche, using which link building methods, etc.
IMO it's valuable knowledge for somebody who wants to make money on the web.
