If you got the newspaper yesterday then you might want to check the Parade magazine.
Inside the magazine is a coupon for a FREE 12 oz. Frozen Lemonade from McDonald's. You should be able to get a completely FREE lemonade without having to make any additional purchase.
I love anything fruity and icy...slushes, Icees, etc. This drink sounds right up my alley. :) If you've tried it, then let us know it it's any good.
