FAQ
How can I redeem my Sonic coupon?
Find the Sonic coupon code on this page, then click into the coupon to reveal more details. If there is a Sonic promo code, copy it, then follow the link to the Sonic online ordering tool. Once you’re finished adding all the burgers, shakes, hotdogs, and sandwiches you want, paste the code in the “Promo Code” box at checkout and apply the discount. Your new order total will then be reflected. Do note that some Sonic coupons found on this page will be automatically applied, and no promo code is needed to take advantage of the discount.
Is there a Sonic senior discount?
Sonic offers a 10% discount or free complimentary drink to seniors over the age of 60, and other exclusive coupons. You’ll need to provide proof of age (i.e. a valid photo ID) at either sonicdrivein.com or at a Sonic restaurant location.
Can a Sonic promo code and Sonic Reward be combined?
Unfortunately, rewards collected within the Sonic app cannot be combined with a Sonic coupon on the same order.
