Another thing I’ve been told about UPS...
It’s very hard to collect from them on shipping damage claims unless THEY do the packing.
And USPS:
It’s very hard to collect from them, period. I know someone who shipped an expensive musical instrument with insurance. The tracking died somewhere between two USPS facilities, and it was never delivered. The USPS refused the claim, even with clear evidence that it disappeared while in their custody.
You need to pack as if gorillas are going to be handling your packages.
