Shipping Preference

Does anyone have experience with an outfit called Global Parcel
Services? They ship precious metals and jewelry using FedEx, UPS and
USPS, but insure to higher declared values (as much as $50-75,000)
than those same common carriers do themselves. They also offer
service to Canada, Mexico, UK and Hong Kong. I’d like to hear your
experiences before signing on.

And… I’m particularly seeking a carrier which will ship gold from
Colombia to the US. The usual suspects (such as those named above)
won’t. Any ideas?
