USPS Priority Mail Flat Rate Prices

USPS Priority Mail Flat Rate means one price regardless of weight (up to the published limit) or distance to any U.S. destination. We look up the current published price for the container you selected and show both the online (Click-N-Ship) and Post Office counter price. Marketplace-negotiated shipping labels (eBay, Etsy, Pirate Ship, etc.) may offer lower rates than shown here. Weight-based and zone-based Priority Mail prices are not covered by this tool.
