Lea Ann at Mommy's Wish List report that from now until February 14, when you buy a dozen Valentine donuts at Krispy Kreme you'll get 12 free Valentine Cards. These special cards each have a Free Donut coupon on the back. Not only do they have sprinkled Heart doughnuts, they also have chocolate iced Heart doughnuts with red drizzle, and Triple Chocolate doughnuts with chocolate Kreme filling, chocolate icing and brownie crumbles on top.
Check out this list of participating stores here to make sure your store has the Valentine donuts and cards.
Of course, the best gift you can give anyone is the gift of your time. Why not make a "coupon book" with coupons for watching a movie (of the recipient's choice), a trip to the park, a walk around the block, working a jig-saw puzzle together, home-cooked meal (or dessert) of their choice and/or any other activities they might enjoy.
