Free Chocolate

If you haven't heard, Mars brand (M&M's) is giving out coupons for a free candy bar each Friday. One candy bar is not a huge freebie, but, free is free! You can sign up each Friday to get one, but there's a limit of 4 coupons per address for the entire promotion.
It says you will get your coupon in six weeks, but I have already received the coupon I signed up for last week. Save these for a b1g1 sale and you can get two free candy bars!
Here's the link to sign up today (Friday):
