Shakes are Half Price at Sonic on Saturday, December 21st
The Winter Solstice means the shortest day of the year and discounted milkshakes at Sonic. Shakes are 1/2 price all day.
Celebrate the turn from short days to longer days at SONIC with your favorite shake, 1/2-price. A great time to try our Holiday Mint Vanilla or Chocolate Shake, or stick with the classic Chocolate Banana Shake. Or, whatever else you dream up!
