It happens with the other two carriers also.I don't know about you guys, but I have had expensive items go missing in usps. One time, I was shipping a $175 knife, and some worker at one of the processing plants must have decided it was worth risking his job to steal my knife, because all that showed up at my customer's door was an empty package with my business card in it. Why would they even deliver an opened package with nothing in it is beyond me...
But no, I've never had it happen with usps since I started shipping 24 years ago.
