Remind everyone that free is always free never pay any money for a free gift. Californians can not collect on any outside lottery including the Canadian, Nicaraguan, Chilean, Australian, etc. Con artists use this method to get money from you for up-front taxes on the winnings, registration fees etc.
Never pay any money up-front to win anything. I always tell them to tell the person notifying you to take the money out of their winnings and send the balance. You will never hear from them again, nor will you get any money.
