Every Friday morning (beginning at 9:00a EST) May 8th through September 25th, Mars will be giving away a FREE chocolate coupon (up to $1 value) to the first 250,000 who submit their info. online at RealChocolate.com. You can get 4 per household. I've already gotten 2 coupons in the mail!
I used one of my coupons as incentive for my kids to be good in the grocery store this last week. Whoever was good could divide the candy bars. Two of the 4 kids got to share 1 Free Twix!
