We only sell postage for USPS® shipping services because when you consider Commercial Plus Pricing® and secret services such as Priority Mail Cubic®, 99% of the time USPS® is the cheapest and fastest way to ship small packages.

Generally, due to surcharges other carriers are only competitive when it comes to overnight delivery or extremely large, heavy packages.

USPS® is also the only carrier that delivers to every address in the United States and its territories, including Puerto Rico and the US Virgin Islands.

Other carriers like UPS and FedEx are not allowed to deliver to Post Office Boxes, so PO Box addresses can only be shipped to with USPS®.
