Flat Rate Shipping
USPS Priority Mail® Flat Rate Envelopes, Boxes & Mailers
Have you heard the phrase: "If it fits, it ships"?
Flat rate shipping with the USPS is as easy as it sounds! With flat rate shipping through the U.S. Postal Service, you can use Priority Mail® Flat Rate envelopes, boxes and mailers to pay just one flat rate when you ship up to 70lbs.
Flat rate envelopes and boxes are available in various standard sizes from the Post Office - at no additional charge. You can use shipping software and postage meter to calculate the exact cost.
The heavier the package, the more you save! With flat rate shipping, the pricing is not tied to the weight of the package. It's tied to the size of the envelope or box and the service you choose. As long as your item fits in the Priority Mail envelope or box (but not over-stuffed!), you'll pay one set postage rate.
