The largest volume losses came in package services (down 10.1%) and periodicals (down 5.1%). But standard mail, the type used most often for commercial mailings, gained 0.2% in volume, to 6.2 billion pieces.
Earlier this week, the Postal Service's board of governors approved a USPS request to eliminate Saturday mail delivery as a way to reduce expenses. Next week, the USPS is expected to present its plan.
