Everyone likes to save on USPS postage, and the post office does make it easy to know what the various rates are. When looking at form 3602-R, you can see all of those rates getting nice and low as you sort to finer zip codes. Which is great, and thats most that the average mailer will need to do.
However, there are some lower rates if you look at the entry discounts. Specifically DSCF and DBMC discounts. (DDU no longer apply, except parcels) DSCF? DBMC?
