I tried to collect on insurance once.
It took months and months, reams of paperwork, a multitude of trips to the post office, come back when the postmaster has returned, rechecking the file, come back in another 30 days, we still want time to try to find it, fill out this other form...
Pretty worthless-
They finally found the package, returned it to me, with no payout, after I had reissued the item to the intended recipient 30 days after the original shipping date.
USPS- I never send anything important through them anymore.
