Hi - Can you please tell me where I can look at the case you mention in your post #4? It seems I may have a similar situation. I mailed a fully insured package (costume jewelry) from NY to Canada last July and the package is lost (you think USPS is horrible? Canada Post has nothing on them). Long story short, insurance claim was denied because they're saying jewelry is a prohibited item. I questioned this at the time of mailing, the clerk AND the supervisor said it was okay because it was costume jewelry, not precious metal or stones. I'm in the process of appealing it now. Very interested in reading up on the other case.
