Apparatus and method for providing dual sliding windows for the purpose of determining postage discount qualifications across invalid and unreadable mail pieces and determining the number of mail pieces to be placed in a mail tray for receiving the maximum postage discount. This is accomplished by storing the criteria for postal discounts in a controller and determining the number of mail pieces that can be received in a tray based upon the thickness of the mail pieces. The system includes a scale that weighs the mail pieces, from which weight the thicknesses of the mail pieces can be determined on an individual basis, and an OCR reader that reads the zip codes in the address block of the mail pieces to assure they are valid and readable, and a controller for performing the necessary computations.
