Freemarket vs flippa



First of no, I'm not comparing the two because flippa is way more established and has a bunch more users in the market place. The other day I was browsing the Internet when I stumbled on free market which is freelancer's alternative to flippa and they allow you the list your website or domain for free and take a % commission vs flippa's $9 listings (still have the same up sell of highlighted posts and premium listings). I wanted to know your guys thoughts about freemarket if you had any and if you thought that eventually you could see it as a contender with flippa?
