The folks behind Freelancer.com have launched a competitor to Flippa and Godaddy auctions. Its called Freemarket.com. The best part is that its free and only charges 5% if a successful deal is made. Might be a better alternative to paying those pesky fees from the other sites I mentioned. So if you have some extra domains or used sites you want to sell check it out.
Freemarket will let people post websites or domains for sale, either at auction basis or with a fixed-price eBay-style ‘But-It-Now’ option. A search on the keyword ‘job’ shows 23 sites related to job boards for sale.
