I have read all about undelivered packages. And that has also happened to me. But does anyone know what USPS, FedEx, ups, etc do with all the packages that are never delivered and never returned? Yes, I realize that most are stolen from or by the buyer. Some are destroyed or stolen by the carrier but their must be some small percentage that is retained undeliverable by the carrier. What happens to those? I am especially interested in the usps.
