I recently received a battered package similar in appearance to the one shown. According to the USPO clerk packages such as mine once battered accidentally are opened by USPO personal to inspect for damage to the contents and then taped back together. I can imagine shipping labels getting exchanged accidentally in such a situation.

My conspiracy theory is that someone did this in order to sow this sort of concern and confusion. But the reality is that it was likely a mix up from usps.
