I certainly am a conflicted moron.
But I think the price negotiation between buyer and seller involves balancing fears.
If you offer a bass for sale for say £1680, and I counter offer £1400, which you just accept, that feels like you are desperate to get rid of it, which is obviously off putting and would probably make me back out.
But if you say ‘no way- but maybe you can have for £1600’ that gives the product a psychological unobtainability’, whilst making me feel that I have earnt £80, which makes the deal desirable.
irrational but true
