The Mystic Stamp Company, 9700 Mill Street, Camden, NYU 13316, sent me stamp that I did not order, expecting me to buy or return. I did neither, nor will I. If Mystic or RMCB (Mystic's collection agency) wants to sending me prepaid mailing materials I will (generously, I think) take the time and go to the trouble of sending them to whereever they want.
