What pricing levels does USPS have?
EasyPost has a special agreement with USPS that allows us to give you discounts below Commercial pricing for certain shipments. This applies to Priority Mail and USPS Ground Advantage mail classes and for most shipments 20 pounds or less, flat rate products, and cubic pricing tiers. Prices in the table below include the EasyPost Merchant Discount that you can’t get at the Post Office. Sign up now and get started.
What is EasyPost Merchant Discount Pricing?
USPS has several pricing tiers that can dramatically impact the shipping rates you receive for your packages. USPS Retail Pricing is the starting tier for pricing. This is the USPS rate you’ll pay at your local Post Office or other retail locations. Up until Jan. 22, 2023, USPS had two commercial pricing categories: Commercial Base Pricing (CBP) and Commercial Plus Pricing (CPP). On Jan. 22, 2023, USPS collapsed these into one Commercial pricing category. Commercial Pricing offers savings over USPS Retail.
But there is another tier that can save you even more money on USPS shipments, EasyPost Merchant Discount Pricing. The rates available from EasyPost are even better than USPS Commercial.
