Sonic: Half-Price Shakes All Day on December 21st!

The links in the post below may be affiliate links. Read the full disclosure.


Sonic is celebrating the Winter Solstice tomorrow, December 21st with 1/2 Price Shakes all day long! I’m not sure that you can ever be too cold for a deal on sonic shakes. 😉 This offer is not valid in conjuction with any other special deals.

You might want to call ahead to verify that your Sonic is participating before you head out.

    I went to our Sonic today, and they said you had to have received a text in order to get half price shakes. Fair warning!

    And toss away those old rules about no shakes for breakfast. If the world is going to end at some point tomorrow, may as well have a fantastic start to the last day!

        You guys seriously rocked that zombie coupon post … I’m still crackin’ up. Wait, Kracken. Release the Kracken!

        Thanks so much for the laughter. Where did I leave that 3rd shake – I’m certainly not going to throw it out 😛
