Are you obligated to give a refund after an item is lost in the mail

[Exhibitman]

Two wrongs don't make a right, Ryan. Just because a seller deals with you shabbily doesn't justify another bad act.

If a seller chooses to do business with stamped mail and no delivery confirmation, he is setting himself up for a fraudulent charge-back. Either don't send stuff that way or don't complain about a charge-back when someone either doesn't get an item or sees a chance to scam. Since the seller has control over the item listing [where he can specify the postage] and the item packing and mailing, he is the one on whom a mail loss should fall. As a buyer all I am obliged to do is pay the costs and mailing costs that the seller specifies. I do that and I'm done. The rest is the responsibility of the seller and fault of the seller if there is a problem.
