Grab an afternoon snack with these restaurant deals!

Sonic Drive-In often offers coupons, deals, and happy hour specials, so you can save on your favorites from their tasty drive-in menu items! Plus, you can almost always find additional offers and specials in the Sonic app AND all-day happy hour menu items!

Through February 15th, you can score any Sonic Drive-In Shake on their menu half-price with your in-app or online purchase with promo code SWEET at checkout! You can use this coupon for any size and any flavor shake! Although prices will vary by location, you should be able to snag one for as low as $1.29 when you order in the app or online! This is a great deal, as happy hour specials do not include their yummy shakes!

Note that you can only use one promo code per order, and it cannot be combined with Combos or other rewards. Mix-ins, toppings, and add-ins are subject to an extra charge, and there’s a limit of 5 half-price shakes per order.

    I’ve had the sonic app and it was hacked recently. Someone ordered a meal in Illinois several states away from me and paid for it using a saved credit card. Then I found online that others have experienced the same thing. I will never use that app again, and hope I don’t have further trouble from this. I don’t know how Apple can allow apps like this.
