I was selling a saw. Pretty good one, compound mitre, slider, 12" blade, and a really nice stand. I don't remember what I wad asking, but it was fair. Let's say $500 for the sake of the story.
Dude gets in touch, asks a couple of questions, and says yeah, he'll take it for that price.
Day comes, he shows up and checks it out. I have it set up and we cut a couple of boards to show him it's all square and good.
He says cool, here's $300.
I say, yeah, uh, we said 5. I'm selling it for 5. Not 3.
He looks at me deadpan and says this is all I brought.
I say well, I'm selling it for 5.
He looks at me and says I drove all the way from *city about an hour away on a good day with no traffic.
I look back at him and say Huh. I bet you wish you hadn't done that.
He just kind of stands there looking at his shoes while I pack the saw back up and he sort of sulks off.
This is extremely common as a sort of all-or-nothing negotiation tactic. They’re hoping that you’ll just go “ah well, I don’t want to bother with getting someone else out here. Just go ahead and take it for $300.” Basically, they’re hoping you’ll fall for the Sunk Cost fallacy, and let them have it for cheap.
