I have read a couple of articles on bartering and it seems some people think the art of bartering is dead and some think it is not.
As a Mercedes enthusiast, I have done a little bit of bartering, but it seems like bartering is declining.
A very simple explanation is:
With the advent of various ways to sell items on the web and the access to world wide buyers, cash is still king.
If one owns an Inverted Jenny stamp, you don't offer to trade it, correct?
You sell it for cash and buy other stamps of your liking.
