I wrap EVERYTHING with fiberglass tape, cheap insurance.
I used to ship 3,500 pounds a day, never lost anything in ten years with UPS, NOTHING was lost!
I did "loose" two car size tires steel banded to a pallet on a truck shipment one time,,,,
somebody needed new tires for their trailer!
A few heavy packages (around 50 pounds) were sent USPS, 20% of the packages were lost or damaged.
I only would ship heavy packages USPS at the customers demand, and I required pre-payment by USPS Money Order.
The customer had to deal with the lost shipment.
I do mail USPS packages to our granddaughter, haven't lost one in a year of weekly shipments to Texas.
