BBC Personal Finance Christmas Quiz

BBC have gone all out with their Radio 4 Money Box program this year offering a ...wait for it,...a digital radio (oohh aahh!!) to a lucky person who gets all 20 questions right in this Christmas competition.
What does the BBC get for your wanton desire to win your very own digitial radio? Your personal contact details off course.
So here we are balancing the balls of indecision. Does the chance of winning my very own digital radio (probably valued at less then US$30) negate the effect of handing over my personal details for which I may become random spam fodder. Tough decision.
I think I may go for the "I might leave that one thanks Tony" option after all.
