...Sedo will take at least $50 of the proceeds (unless it's a BIN on certain platforms, ie it cannot have come thru their MLS) and that for me is a deal killer, I may get a $200 offer but I refuse to give Sedo $50 :-(
I don't begrudge Sedo the money, I feel they earned it. If they are not your only sales venue, if you are trying to sell your stuff everywhere, and yet Sedo is the one who keeps making sales for you, well then that's great.
I sell more via Sedo's MLS than any other venue, including direct email contact, domain forums, and other listing sites. Everything of mine at Sedo is "Buy Now" pricing. Most get sold by GoDaddy when businesses go there to register (not to buy
per se) and Sedo automatically sucks the domains off Dynadot (my registrar) and delivers them to GoDaddy.
If I got a domain for under $25, and renewed it once or twice, and Godaddy sells it for $200 so that Sedo transmits $150 to my bank account, and it all happens automatically while I sleep, so that all I have to do is keep stocking the Sedo account with domains that will sell within a few years... well that's just fine. It's a decent way to earn extra cash. And most of these domains sell for way more than $200 anyway; about $450 average.
If they're not good enough domains to satisfyingly sell when paying $50 to the venue, then they're probably not good enough to keep in stock. Dump 'em at a forum.
Unless you are an underemployed citizen of a third world country, it's too much work to sell them yourself just to make an extra $50 when Sedo can sell twice as many of them for you while you sleep.
