The Postal Service recently filed for a change to Reply Rides Free with the Postal Regulatory Commission (PRC) to let customers mail their qualifying pieces weighing up to 2 oz at the 1 oz price. If approved by the PRC, this change will go in effect on September 1 through December 31, 2011. The extension of Reply Ride Free is intended to simplify this program for participating customers. The Postal Service intends to extend the 2 oz free rate to First-Class Mail Presort and Automation letters (NOT First-Class Mail Single-Piece letters) as of January 2012. Earlier implementation is not feasible.
