No .. the onus is on the SHIPPER to make sure he's protected in case something bad happens.
It's shipper's responsibility to make sure the item gets to the buyer. And when it doesn't (like this case) the shipper should provide evidence of shipping (self-generated label or post office receipt - both will show weight of the box) and evidence of receipt (signature required). Shipper can get insurance or bear the risk of not insuring the item. If seller can't provide this, the seller should provide immediate refund to the buyer.
If I were the buyer in this case and the seller is not being cooperative, I'd start the PayPal dispute. If he paid with credit card (which is a smart thing to do), he should also inform his credit card issuer.
Hidy Ho <--- often insist on shipping method that is tracked but never insurance when buying (however, do both when selling)
Hidy, It depends on the shipping terms that were negotiated. In this case odiously shipping terms were not discussed. A global reference is Incoterms. If you want to trust the shipper more power to you. But for my money I will protect myself and discuss shipping terms prior to any transaction.
Did you pick the Ebony or the Cocobolo?
In this case Seba declared how it would be shipped and that it would be insured.
