Unlike FedEx and UPS, USPS has delivered mail and packages six days a week for years. Given the rising cost of shipping, obtaining free packaging is a definite perk. You can get free boxes and envelopes from your local Post Office or through the USPS store online. The United States Postal Service also provides complimentary packaging. There are no additional fuel costs or delivery expenses to be concerned about. That means they'll ship it any distance if you can fit it in the box. For Priority Mail shipments, the USPS does not tack on any surprise surcharges and charges flat rates.

Some shippers are attracted to USPS because of the unpredictability of accessorials. However, based on the zone and weight of the package, the charges for Priority Mail and Priority Mail Express services have increased by 3.5% and 1.2%, respectively. The USPS shipping rates for 2021 had a minor impact on First Class Mail and Flat Rate pricing. The US Postal Service (USPS) is an independent agency of the US federal government that is responsible for providing postal service across the United States, including its insular areas and associated states.
