In this case insurance would not have helped cause any shipper would say insufficient packaging and shipper would not be liable. Given the flimsy box it would take a miracle for it to arrive undamaged. Fedex, UPS, USPS none would cover that damage even if fully insured, none of them. So saying it should been insured is pointless if its not packaged sufficiently.
Restoration guy is totally negligent on packaging. If he does not fully reimburse he should be banned from this site.
