I think that if it is still listed with this BIN price it may mean that nobody is interested in this name for that price, so probably the name isn't worth that price...
I've never thought about it this way. I'm curious if you're so competitive that you base a domain's worth on what other domainers think?
People with real interest on the domain will take the time to write and inquiry the price.
I am disturbed how my Make An Offer names listed on afternic are portrayed on godaddy. If an end user does an exact search for my domain at godaddy, a form pops up and you have to put in your full contact information and possibly your mother's maiden name LOL. In the background, there are all sorts of other names for sale making it easy to purchase an alternative.
BIN price makes it easier for all parties - Sedo/Afternic, buyer & seller.
I think it depends on the TYPE of domain.
Here's my experience:
Sedo = buyer AND seller unfriendly including no phone support and weak email support
I listed a .TV for $250, it sold and sedo got a $50 commission for making it happen. Then they asked me to renew it myself, according to TOS requirements, and I said no, cancel the transaction. They continued with the sale because the buyer would renew himself.
A 100 step process ensued because of the time zone and third party relay and unnecessary control sedo has concerning transfer. It took 3 weeks to complete.
It's too much rigmarole for an end user who has the power to BIN and still renege on the purchase.
I had to pay a commission and still do all the leg work like manually submit transfer codes. The buyer messed up so I had to call name.com to issue another transfer code. Then I had to issue an invoice. Sedo won't do it because they say they don't own the domain and are not the seller. Then I had to create a Word document, download an invoice template and turn it into a PDF to upload it to sedo. Then the buyer has to accept the invoice.
Afternic = partially buyer friendly and very seller friendly. Good phone support and you wake up to emails like: "Escrow started for whateverdomain.com"
4 days later, they wanted to know how I wanted to receive my money.
My only complaint with Afternic is the dashboard is clunky with endless error messages, domains in perpetual "review" status, and I missed out on 2 cancelled Make an Offer deals because I never got the emails.
BIN+Afternic = $$$
