What are you missing here? Well nothing maybe but I happen to still disagree with the statement above, I believe it is relevant,
A- If you don't take into consideration what you believe is a fair price to the other person how do you determine the amount you will offer?
B- I do fairly well with my version of "Economics 101" and I don't need to be unfair to do it.
I am not saying pay more than the asking price and I am not criticizing you, I just believe in being fair to everyone and humbly disagree with the assertion of fairness being irrelevant.
