The Incentive

When you buy one of my books I will drop a special numbered ticket with your name on it into a bowl. The bowl currently holds a maximum of 200 special numbered tickets. When the bowl is full I will pick one special numbered ticket from that bowl and invite the name on the special numbered ticket to decide between being my honored guest on a once-in-a-lifetime free tour to Cuba...or...going for instant gratification and instead taking $500, in cash.
