Is Sonic Doing Half-Price Shakes Right Now?
Not as a national offer at the moment. Sonic’s most recent official announcements (October 2026) cover the winter menu, a refreshed $7 Big Deal Meal and 50¢ corn dogs on Halloween, but no half-price shakes. Individual restaurants and the Sonic app sometimes run their own shake discounts, so the app is the quickest way to check.
Update Oct 29, 2026: Sonic’s website currently lists the $7 Big Deal Meal with a Sundae at drive-ins. The refreshed version with small Premium Chicken Bites is in the Sonic app from Oct 26 and nationwide from Nov 2, 2026.
How to Check for a Half-Price Shake Deal
- Open the Sonic app, choose your restaurant and look under Deals. App-only offers appear there.
- Check Sonic’s official social accounts. Big promotions like Sonic Nights are announced there and in the Inspire Brands newsroom.
