Out of thousands upon thousands of boxes shipped across the world, we haven’t had one single case of a truly lost package. In almost every single scenario, the package arrives 2-3 days after the post office marks it as delivered, or the recipient discovers someone living in their house put it somewhere. Be sure and ask your neighbors to see if your box was accidentally delivered to them, ask the people living in your house if they placed it somewhere, and contact your local postal delivery service to ensure it was delivered. Ultimately, if the postal service has marked the box as delivered, there is little we can do. If you believe the package was stolen from your porch, please file a theft report with your local authorities. Theft of a USPS-delivered package is a federal crime.
