There is a ton of debt that needs to be made up in the United States Post Office (USPS) and this Friday is the beginning of some rate hikes and some later delivery times. It's part of a ten-year plan to try and put a dent into the one hundred sixty billion dollar debt they are facing.
If the United States Postal Service has its way, Americans will see another hike in the price of postage, and that hike will happen sooner rather than later.
