On November 11 I sold a book to an apparent drop shipper who had me mail the book to someone in Pittsburgh, Pennsylvania. The shipment shows as delivered on November 14 but today, December 17, the book was returned to me as undeliverable - return to sender. Also, thereâ€™s a label on the package that says postage due of $8.38, but I donâ€™t know if that is being charged to me or to the drop shipper. Iâ€™m confused as to what I should do next. Any advice?
