Last time I got insurance for a USPS package, which held an ultra-rare MARVEL poster, a forklift ran over it in Grand Junction, MI. I spent months convincing USPS that they dropped the ball and spent even more time proving that the poster was as valuable as I insured it for. To actually get through to the USPS dept who handles claims tested the limits of my tenacity. After I got the settlement, thank goodness, USPS kept the poster for “research” purposes. I had no say in the matter. FedEx is the way.
