Pay attention, there could be free money in your mailbox

Valpak is that envelope you get in the mail sometimes that is stuff with coupons and deal offers. Some of the 37 million people who get the mailers never even look inside.

Susan Stiner says, "I Recycle it. Toss it. I just always throw it away."

But you may want to start paying a little more attention to what's inside your Valpak envelopes. The company is now putting vouchers for $100 in them at random.
