I wish I had a Sonic, because I would be in heaven if I could get a Cherry Limeade Chiller for 99 cents. If you do have a Sonic then I have great news for you. You can go here to sign up and get a coupon for $0.99 Sonic Chiller. After you sign up you’ll receive a confirmation e-mail. After your confirm receipt of this mail you will receive the link to the coupon which will have your e-mail address. The coupon expires within 10 days after it’s delivered and printed, and it’s only available until August 31.
Enjoy!
