The proposed prices, approved by the Postal Service Governors, would raise Shipping Services product prices approximately 3.5 percent for Priority Mail service, and 1.2 percent for Priority Mail Express service. Shipping Services price increases vary by product.

The Governors believe these new rates will keep the Postal Service competitive while providing the agency with needed revenue.
