Use original packaging to secure cartridge - double box with plenty of poly puffer, styrofoam popcorn etc. Pick FedEx or UPS if you can't stomach USPS. Insure for whatever amount you can support with documentation. Say Hail Mary three times and drop package off. VAS and others will usually send back via USPS unless you specify - at your cost - make sure you specify insurance amount. USPS only offers insurance up to $5k for priority mail.
A lot depends on your risk tolerance. I only insure for a couple of hundred dollars - just to let them know there's something valuable in there. There is always a possibility that the package may get lost, but the probability is low. It has happened to the unfortunate few.
