I know there is such a thing called hand-cancelling the invites so that they do not have to go through the machine. I have also read on the boards that even if you get your invites hand cancelled they still go through an additional 3 machines any way. Also, I asked at the Norman post office about it and they said that it costs .20 cents per envelope in a hand-cancelling charge. My invitations will be light no RSVP's on the inside but they will have a ribbon flat at the top. I just wanted to get some local thoughts on this whole hand cancelling thing and what others experiences were with robboned invitations and the mail.
