Unlike some other shippers, the Postal Service does not add surcharges for fuel, residential delivery or regular Saturday delivery. The Postal Service has some of the lowest letter-mail postage rates in the industrialized world and continues to offer a great value in shipping. The proposed domestic Priority Mail Flat Rate Retail price changes are:

Regular Flat-Rate Envelopes, Legal Flat-Rate Envelopes, and Padded Flat-Rate Envelopes would increase to $7.95, $8.25, and $8.55 respectively. The Medium Flat-Rate Box would increase to $15.50, the Large Flat-Rate Box would increase to $21.90 and the price of the APO/FPO Large Flat-Rate Box would increase to $20.40. If favorably reviewed by the PRC, the new prices will include an increase in the price of a Small Flat-Rate Box to $8.45. The Governors believe these new rates will keep the Postal Service competitive while providing the agency with needed revenue. Although Mailing Services price increases are based on the consumer price index, Shipping Services prices are primarily adjusted according to market conditions. Shipping Services price increases vary by product. 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.

WASHINGTON, DC - The United States Postal Service filed notice with the Postal Regulatory Commission (PRC) today of price changes to take effect Jan.
