By presorting and automating your mailing, you save postage. Because you are putting your mailing into a presorted zip order, you save the postal service from doing that work. And by applying the barcode before entering your mail into the mail stream, you save the postal service from deciphering the address and adding the barcode themselves. So, because you have done this work for the postal service, they charge you less in postage.
