Probably would have been cheaper on them to just get the insurance.
Since I paid for the insurance, a fact clearly shown of the itemized invoice that I received from them, it wouldn't have cost them anything to insure the package.
I was told that they didn't insure firearms that were being returned from being serviced because so few were lost or stolen during shipping and any decision regarding compensation was at their discretion unless the customer specifically asked and paid for the insurance.
