Sonic is running a limited-time promotion on March 13, 2019 where anyone can get shakes for half the regular price.
The offer is available all-day at participating locations on Wednesday, March 13, on the purchase of the chain’s Classic and Master Shakes only.
While no coupon is required to take advantage of the offer, there is a limit of five shakes at the discounted price.
I always recommend mentioning deals of this nature when placing your order to ensure you get the deal, and restaurant participation.
Sonic’s Classic Shakes lineup includes:
- Caramel Shake
- Chocolate Shake
- Strawberry Shake
- Vanilla Shake
- Hot Fudge Shake
- Peanut Butter Shake
Sonic’s Master Shakes lineup includes:
- Oreo Peanut Butter Shake
- Oreo Chocolate Shake

Shake availability may vary by location.
