I'm going to the car dealership soon to buy a used car. The price is a little high, and I was wondering if there were any good ways to talk down the price. I want to get from 25,995 down to 23k. Like if anyone took psychology or something or knows how to mind fvck with people to get them to agree with you, that would help a lot. I was thinking I'd get him a pop from a vending machine or a coffee. I read in this one book that the feeling of owing someone something is very powerful. Any ideas?
