System and method for printing correct postage for batches of mail with presort discounts

A method and system of providing postage wherein delivery fee discounts are provided based on one or more sorting levels in which mail pieces are run through the system twice. In the first run, postal codes are obtained from the mail pieces, a running tally for each participating sorting level code in each sorting level is kept, and for each code in the highest sorting level that has a tally that reaches a predetermined minimum, an indicium reflecting the highest discount is printed on: (i) the mail piece whose postal code caused the tally to reach the minimum, and (ii) any mail pieces to that postal code that are processed thereafter. In the second run, for each mail piece not having a printed indicium, an indicium is printed which reflects a proper sorting level discount, if any, based on the postal code obtained therefrom and one or more of the tallies.
