If you're a NamePro's member, you'll be pleased to hear that you can list your domain name for sale in the Live Auction... for free.
The live auction is held twice monthly and features domains for sale in a dynamic online even that is actually hosted by a live auctioneer team. Domains will be added immediately to the silent auction and will become eligible for the live auction when a verified bid is received that is within 50% of the reserve. Reserve prices are required for all auction lots and a 5% final valuation fee is due upon successful transaction.
There are some restrictions of course. NamePros will not sell explicit adult names, sub-domains or non-standard domains, domains expiring in less than 30 days (unless renewal is included) or IDN domain names (unless they are identified as IDN with the punycode in the description).
