Birthdays and ice cream just go together. And if you sign up for the Cold Stone Birthday Club ONLINE, you’ll get a FREE ice cream creation just because it’s your birthday. You have to be 13 or older to sign up, but if you’re younger than that, a parent or guardian can do it for you. Then show up on your birthday for your FREE frozen treat. If you sign up for the birthday club, you’ll also get other freebies and deals throughout the year, starting with a two-for-one deal.
