You can get a coupon for a free box of Kraft Macaroni and Cheese on Facebook. Just visit the Kraft Macaroni and Cheese Facebook page at 12 Noon EST today (1/24) and click on the Macsurance link on the left. The giveaway is supposed to go live at that time and you will get instructions on how to get this freebie. From what I understand you have to watch a short video and share with a friend. Then enter your information to have the coupon mailed to you.
I could not find out exactly how many coupons they are giving away. but I do know that these go fast, so make sure to check out the Kraft Macaroni and Cheese page a few minutes before the offer goes live.
