Un cancelled/voided stamps twice in a row? I recently got a book in the mail from another person (thanks to my wonderful book trading club website) and the stamps weren't cancelled/voided. I thought to myself "sweet, free shipping for the next book I send." But then today I got another book and the stamps weren't voided/cancelled either. Is this some sort of huge coincidence or is there something special about media mail or what? And have you ever seen 80 cent stamps before? I thought it was pretty cool.
