From USPS News Link:
The changes will help create a world-class distribution network, on par with best fulfillment practices that are currently being used by other large national retail operations. And they will have no immediate effect on the stamp ordering and fulfillment process. Post Offices should continue ordering stamps as usual, until further notice.
Future changes include the closing of Stamp Distribution Centers in Atlanta; Binghamton, NY; Kansas City, MO; Phoenix; and Portland, OR. The closings will take place no later than Sept. 20, 2014.
The new, consolidated Stamp Distribution network will operate primarily out of a location within the Stamp Fulfillment Services facility in Kansas City, MO, and a secondary location in Dulles, VA. This new network is scheduled to launch by Sept. 20, 2014.
Changes in the fulfillment system are needed to create a distribution and fulfillment operation that supports the growing number of direct-to-consumer stamp orders received from online channels, including eBay. The new system also will improve stamps distribution to more than 34,000 postal retail outlets and partners such as Costco, Wal-Mart and Staples.
The changes include greater use of automated equipment to provide order processing 7 days a week and fulfillment and delivery times of 5 days or less. The consolidation also will improve inventory management, reduce destruction of stamps and help keep retail offices fully stocked with a variety of stamps.
Employees affected by these changes have been notified according to established employment guidelines and procedures; for affected bargaining unit employees, notifications and procedures are in accordance with the applicable bargaining agreement.
Further information will be announced as it becomes available.
