The abrupt bankruptcy of APX Logistics left a lot of packages stranded. The consolidator normally picked up a million packages a day and routed them through the USPS for delivery. The Postal Service expects to have all of them on their way to customers by the end of the week.

USPS is adding resources and increasing the number of drop-ship appointments at Bulk Mail Centers to deal with packages accepted by APX prior to the company's filing for Chapter 11 bankruptcy protection March 16.

"We are working with APX officials to move remaining on-hand mail volumes from the company's network to postal facilities and, by week's end, expect all APX packages to be within our system and on their way to customers," said Azeezaly S. Jaffer, vice president public affairs and communications at the Post Office.
