Happy St. Patrick’s Day from Sonic! Celebrate with half priced shakes all day, Thursday, March 17, 2016!
It’s as simple as that! No coupon needed! Just go pick a shake and get it for half price! They have a ton of shakes to choose from too! So no one would fault you for going twice. 🙂
And half price shakes after 8pm is back too! So if you find a shake you like on the 17th (I recently tried the Dulce de Leche creamery shake – YUM!) you can indulge for half-price after 8pm!
