I'm not sure what was up with this domain seller. I can understand wanting to play hard ball as most domain buyers aren't very serious, but it should never be done to the degree that you lose your potential customer's trust. He (could have been a she) certainly wasn't doing a good job of making me feel comfortable with the domain transaction.
I don't have issue with paying large amounts for domains (based on stats and potential development value), but i'm not going to walk into the negotiation with a blank check and say "here you fill this out with whatever amount you want." Simply, some people think their domains are worth millions and others have no idea, so my first offer is always low. I mentioned to the seller that the domain had no development value to me because I encounter a lot of domain sellers that jack up the price sky-high when they find out you want to build a business around the domain. I absolutely hate when I call about thislongassdomainthatissofrigginlong.com and they say, "$24,000."
I guess I'm left wondering what the buyer was thinking. Did he think I was going to just say "$4 million dollars?"
