Well I am financially tied up in this thing, but it will probably turn out well. I sold "Mayan Apocalypse" insurance policies and included a "genuine" Mayan talisman to protect the wearer from any effects of the coming disaster. What really sold them well was the "triple your money back if it doesn't work" guarantee.
If the world doesn't end, I don't have to pay off on the insurance and I can credit the charms for it. Of course if the world ends I will have to take out a mortgage on the house but I'll worry about that if it happens
