Courier, Express, and Postal Observer: Yesterday at MTAC, The Postal Service announced that it will begin beta-testing parcel lockers with a brandname gopost in Northern Virginia on December 6. The beta test will include 25 sites when it goes live. When the test begins, the Postal Service joins Amazon in testing parcel lockers for delivering parcels to individual consumers. The Postal Service's gopost lockers differ from Amazon's in two ways . First, they are designed to accept parcels as well as deliver them. It is unclear from the picture if gopost will allow customers to pay for a parcel and print a shipping label like PackStations do forDeutsche Post's (DHL's) customers.
