And the seller/loser is yellow68runner

I am confused here.
The USPS I ship with does offer insurence and tracking if you pay for those options.
And always beats UPS's prices.
I have never had anything lost or damaged by the USPS.
Everything I have had shipped to me via UPS was received damaged or destroyed and UPS never paid a claim for any (Always determined to be "Improperly Packaged" by shipper).
So.... I never use UPS anymore and I always request sellers to me not use them either.

My 2 cents worth.
