UPS/FedEx has sucked for a while now, rarely are they cheaper than USPS
Well yeah, USPS should be cheaper. They tend to get bailout money from the U.S. government due to operating at a loss e.g. https://www.reuters.com/world/us/us-senate-approves-50-billion-postal-service-relief-bill-2022-03-08 , UPS/FedEx on the other hand just raise their rates / change services to keep their shareholders happy.
In theory if the USPS was allowed to increase rates as much as any private company then they would be as expensive, if not more, vs UPS/FedEx.
Wonder if he was ever really “missing” to begin with. Maybe the family was able to claim life insurance money, or there was some other reason he needed to disappear. Then after 30 years there was no point keeping it up so he was mysteriously found with no explanation.
