USPS has several pricing tiers that can dramatically impact the shipping rates you receive for your packages. USPS Retail Pricing is the starting tier. This is the rate you’ll pay at your local Post Office or other retail locations. There is also Commercial Pricing which offers discounts over Retail.
EasyPost has Merchant Discount Pricing 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. Best of all, these discounted rates come without any contracts, fees, or volume minimums.
