Don't be so quick to toss that junk mail.

My friend, Kim Matas, received a letter from Arbitron, asking her to take part in a radio survey. And, inside it, was a crisp $1 bill. It's not much. But, why throw away free money?

The letter says only a select few were asked to take part in the survey, but if you get a letter from Arbitron, open it up, before tossing it.
