What is “Flat Rate” Shipping?
For one rate flat rate, you can send a package weighing up to 70lbs anywhere in the continental US through the United State Postal Service. Priority Mail® Flat Rate Shipping is one of the most widely used services at the USPS. Shipments sent using the Priority Mail flat rate service arrive within 1-3 business days – this also conveniently includes Saturdays!
Below you’ll find a flat rate pricing chart that compares flat rate pricing to standard shipping prices. We’ve also outlined the difference between Retail and Commercial Base pricing.
Retail Pricing – Amount charged at the Post Office counter.
Commercial Base Pricing (CBP) – Discounted pricing available to recurrent Priority Mail customers that frequently use specific postage payment methods. You can get CBP using shipping software.
