I've recently made a few offers for knives on the exchange. A couple of the sellers were asking for $$ Net to them on their posts. When I made the offers, I assumed that this would be the total price paid, shipped. After my offers were accepted and the paypal was sent, the sellers came back asking for paypal and shipping fees. I'm curious why sellers that list this way can't add in the shipping/other fees and list the total price of their item? IMO, it should be the sellers responsibility to do their homework and ask a total price (with their fees already included). This would solve the problem of ambiguity. I know shipping varies but not by that much. Both deal were lost for a dollar amount that ranged from $3-6. Am I totally off base here?
