The price of sending packages, letters and bulk mail through the U.S. Postal Service went up on Sunday, to the dismay of mass mailers and e-commerce sellers.
The product and service price increases were telegraphed earlier this year and received approval from the Postal Regulatory Commission.
The price for domestic shipping service increased about 6.3% for Priority Mail service, 7.1% for USPS Ground Advantage and 7.6% for Parcel Select. Ground Advantage, introduced two years ago, is an economical service for shipping packages up to 70 pounds in two to five business days. It replaced three other parcel delivery products. The minimum charge for small packages now exceeds $4.
Meanwhile, the price of a first-class mail stamp increased to 78 cents from 73 cents. Letter and postcard rates on average increased 7.4%.
