Ha! Actually, they screwed up the "not deliverable" part, too. The address was just fine. Then it got stuck in this endless loop, where it would still be to this day, had I not called the Nashua, NH post office. They gave me the secret phone number of the distribution hub honcho, who manually went through all the bins to find my package. He told me that they've had boxes get caught in a loop like this for months on end until they finally just disintegrate.
