So I sold a domain name back in March 2017, to an individual who made an initial offer of $400., on Dynadot Marketplace. We closed the deal at mid four figures, a fair price, maybe even on the low side, for a five letter domain name of mine that consisted of a real word plus a single digit number. Buyer was in California. Since the sale I have been monitoring the domain URL, wondering why it it is still resolving to my name servers, and nothing has happened with it. Today I noticed that the domain name was finally not resolving, which meant that nameservers were in process of being changed. I googled the domain name, and Voila! there it was, a federal trademark registered shortly after my sale, for a new product from a major US corporation that is located in the same city and state as the individual buyer. Obviously the buyer works for the corporation, but didn't want to alert anyone to who wanted the domain name. After the initial $400. offer, I wrote back immediately that this was a premium domain name and that $400. was not going to cut it. I eventually quoted a price, and he came up to about what I wanted, and we closed the deal with the escrow fees split. Just goes to show - even big companies try to snatch domain names cheap. Everyone wants a bargain - even to the point of a big company trying to save a few bucks lol by splitting escrow fees. Luckily, I do my research and comparables and have a sense of what my domains are worth, which in my opinion anyway, is a lot.
