I recently began listing a domain for sale on Flippa, but abandoned the listing process once I realized the fee for listing was $39, and I didn't expect the domain to bring in that much to make it worth the listing fee. I'm sure it's a good place to list higher-priced domains, just not for me. I know people will say advertise them here on the forum, but practically every small forum has a marketplace these days. What's the best online marketplace (forum based or not) for maximum visibility when selling a domain name?
