If you require postage with a unique or custom value, you can specify your own price.
For example, suppose you have a 2-pound package that you would like to send by Priority Mail. Because the package is over 1-pound, the rate depends on the ZIP codes that you are sending the package from and to. The USPS website offers assistance in calculating what the postage should be.
Optionally, use the Calculate Postage feature on the USPS website to find the correct rate for your package.
For assistance with selecting labels, see Select Labels on a Sheet.
