I sold a domain years ago. I got a random email from someone asking me to buy it. Upon some research, it looked like that person was collecting domains names under the same topic. I did some initial negotiation but wondered if others would be interested. I was lucky and found someone else that was interested but the lucky part was that I had found a person that was the first persons nemesis. They had both tried to buy the same set of domains in the past so I think I stumbled upon two fierce competitors. I wasnt able to figure out how to negotiate between them over email so I just but it on eBay and let them bid on it through that. I ended up with at least 10x more than I was originally looking for.
