If you see the message "Shipping Label Created, USPS Awaiting Item," it means that USPS has picked up the package from our warehouse but they forwarded it to the next point without scanning it.
A package is not considered to be "accepted" and in the USPS mail stream (even though the USPS mail carrier picked it up) until it is scanned at our local post office or distribution center, but they often miss the scan too, incorrectly leaving the tracking status as "Shipping Label Created, USPS Awaiting Item."
