paying a sellers paypal fees

here's my .02... you are the seller/ buyer have 2 options
if buying/paying what the asking price is, then there is no reason for the fee.
if you are buying and beat seller down farther than he is asking, expect to pay fee or don't buy.
if i own a wheel for 100 and i ask 110 i covered the fee. if you want to beat me down to pay the 100 you pay the paypal fee or send a money order (which the post office charges a fee anyways).
