I've only had 2 instances where insurance was needed. 1st was a USPS package of brass drop pieces I purchased of a Facebook machining page from a individual. I finally got a message the package was undeliverable/lost, or some such. Went to the local postmaster, and it was determined that the pkg was in the "lost letters" facility. If it was lost, how did they know that? Anyhows the postmaster said that usually a package would break open, and contents may have been lost. It was a priority box. The postmaster also told me to contact the seller, as he had insured the pkg for $500. I think it was $40. I paid him... lol.
2nd, ordered a Simson Luger off ShotGunNews - yes, pre internet days. Customarily purchases came with a 3 day inspection. Didn't meet my expatations, so sent it back, called seller to inform, he told me he didn't see me doing that, and had already spent the money. Hmm, What to do now? The seller called me back a few days later, saying the pistol arrived damaged, and he returned it. So, I was happy I insured the return for what I had paid for pistol, $1200. I had to go to the UPS drop store, to meet the UPS insurance adjuster. The pkg damage appeared to be a maybe 3/8" hole in the side of box. On the inside, ever what made the 'hole' hit the wood grip, shattering it, crushing the magazine, and breaking the wood magazine base. The adjuster, who happened to be a gun guy, remarked that he'd never seen a pkg damaged like that, and suggested I get a appraisal of before and after value, since the grip and mag base were numbered to pistol. The adjuster saw the original appraisal, reduced value appraisal, asked if I'd be happy with a payout of the reduced value, and me keep the pistol. Oh yes, worked for me! After a week, got a call from the insurance dept, asking "so, we pay the claim, and you keep the pistol, this doesn't seem right". I replied to check with the adjuster...
