The beware against Nightwish was removed from the community.
Upon much further research; a seller in the United States is still fully responsible for the safe delivery of a package even when it is out of their hands and with the chosen shipping service. Paypal also includes this in their TOS: https://www.paypal.com/ga/webapps/mpp/ua/useragreement-full
Please always make sure you insure your packages, as it's more for the seller's safety than the buyer. Keep your receipts.
We apologize for our mistake and hope the two parties involved can come to a mutual resolution soon!
