Where they packaged one of the speakers they should at least be responsible for the damage on that one. About 10 years ago I purchased a Parasound amp on Audiogon . UPS packaged it using those cheap air filled plastic pillows . Half of them were deflated. I contacted the seller to inform him the amp was damaged and I sent pictures. He contacted UPS who had a driver visit me. After inspecting it he couldn’t believe the packing. UPS honored the claim.
Fedex is no better. Where I live most of their drivers are independents. I have had packages that were supposed to be signed for just left on the porch and some packages were left in the rain.
