It's an item that was paid for and not delivered as promised. It's not like anyone is expecting them to find a book in a coffee shop and return it to the owner for free. Postage is on them. And they claim that they do. Their claim is that they look through the items to find any identifiers to find out who to return it to in all cases. But in reality, they only do this with insured items because they effect the bottom line. I will also say that the USPS is rather amazing at what they do when everything works as it should. As a test, I once sent myself a postcard from the other side of the country. The only thing I put on the back was my first name and my zip code. It actually made it to my mailbox. Of course, in most cases that wouldn't be enough information. But I am from a small town and we were the largest single shipper, so the postmaster knew me by name.
