I got a multi-thousand dollar domain name for a few hundred dollars, I just kept up a regular dialog with them and made it clear what I was willing to pay. They kept negotiating, I kept to my number. Eventually we came to a reasonable compromise and it's mine. It wasn't something others would be interested in so it was clear after a couple of years years I was their only buyer.
