Amazon has built up a vast logistics and fulfillment operation across the country, but it still relies on the Postal Service to handle some last-mile deliveries when it's not using its own contractors.

First Class Mail envelopes, flat rate envelopes, and USPS Priority Mail offer the lowest rates for small packages. Another option is to use cubic pricing. Cubic pricing is a special USPS service that offers lower shipping rates when sending small, heavy items that are under 20lbs with USPS Priority Mail.

USPS is the only carrier that can ship to PO boxes. Plus, there are limitations when it comes to the size of the parcel that can be delivered. If your package doesn't fit, USPS will hold your package aside.If a customer enters their address as a postal box, you might reach out to them.
