That little
black box is your ticket to
success. The metered mark isn't pre-paid in the same way that a
stamp is pre-paid. The Direct-Mailer hasn't paid a dime beyond printing
costs on that envelope. When the Post Office gets it in the mail again,
they log the account and charge him or her for the return postage. If
you throw it away, they don't get charged.
