This coupon offer from Save.ca and General Mills Canada has got your snack time covered for when the feeding frenzy of school children come bolting through your door and descend on your kitchen with ravenous bellies after a long day of play and learning. Right now when you buy 2 of the specially marked boxes of either Nature Valley granola bars or Betty Crocker child snacks you can qualify for a coupon that will give you a FREE 1L carton of chocolate or white milk.

The boxes at the grocery store will indicate if they are part of this ongoing offer, and on the inside will include a pin that you will have to enter at this website after you have collected two of them. After you have entered in your pins, you will receive a coupon that can be used to pick up your free 1L carton of milk from your local grocery store.

Save.ca is only allowing you to use this free milk coupon on chocolate or white milk, so you won’t be able to use it on specialty milk products like Omega 3, calcium and/or Protein enriched, Lacteeze, Lactaid, Lactose free and any other filtered milks. There will also be a maximum value of $3 allowed for this coupon, but seeing as most of us buy milk regardless of whether it’s free or not (especially if you have young kids in the house), this is an opportunity to save on one of your household’s most popularly stocked items.

You have until May 31st, 2015 to cash in on your free milk offer, but it won’t be available in Quebec, New Brunswick, Nova Scotia or PEI.
