There is the price you want to sell it for and the price I want to pay. Everyone is happy when they happen to be the same price. Otherwise it is just a conversation.

I don't think I've ever been upset about not getting the price down low enough. I am sometimes envious when someone tells me they bought the same thing I did and they got it for less. Then I remember that I was happy when I bought the item and the value of an item is relative to what the buyer thinks it is worth.
