Shippers know their stuff as they deal with frequent fraudulent claims.
For anything irreplaceable or of great dollar value it is wise to
have a sales receipt or appraisal as well as photos just in case.
Regardless of how much you insure your item for shipper will only
pay claim to amount item is actually worth i.e. replacement cost.
In the event of damage failure to comply with shippers packaging
requirements will result in claim not being paid.
Cushioned packing must be equivalent to the items volume on all sides.
i.e. a 4" cube should be shipped in a minimum 12 X 12 X 12" carton,
surrounded completely by appropriate packing material.
