My lovely friend Adrianne posted this on FB. If you go to the Cold Stone Creamery website and join the birthday club (and while you're at it, sign up the kids and husband too!) and you will get a free ice cream (with mix ins!) for your birthday. Mmmm. Free ice cream. You really can't beat that.
Edit: The easiest way to do this is actually to create a My Cold Stone account for yourself first. Then once you get the verification email, you can enter other family members under your account for the birthday ice cream.
