Give credit where credit is due.
Yesterday I got an email from someone interested in one of my domains.
“I found your domain on BuyDomains,” he stated.
But he thought the price I listed on BuyDomains (via Afternic) was too high and wanted to negotiate. Rather than call BuyDomains to negotiate he emailed me directly.
We worked out a price, and then I changed the price at BuyDomains to what we negotiated and told him to buy it through them.
It could be tempting in this situation to circumvent the marketplace to save on commission. But that would be unethical.
The buyer clearly stated that he found my domain on BuyDomains. So the marketplace is responsible for him contacting me. It should be part of the transaction. The same goes for a case in which a broker brings in a lead for you.
