The
most recent changes to postage rates occurred in Spring/Summer 2007. There is ongoing debate about when the next
change will occur but these links take you to the most current tables! To interpret these tables, we recommend you
work with your local mail house/lettershop because
very specific steps need to be taken in order to qualify for discounted
rates. Also check out the great
USPS Discount Mailing Services webpage at http://pe.usps.gov/text/dmm200/discount.htm
For more explanations, can also look on the USPS site
