Idle question, something I've never thought of. Say, for instance, I like the auction ending price and decide to suck up the cost of shipping for goodwill. So, I refund the charged shipping cost to the buyer, whom I then own for all time to come because I just arbitrarily lowered the price I charged him.
Does the buyer pay Paypal fees on that incoming money? I actually have an auction ending tonight that I might do this for.
