Sonic is celebrating the start of a new school semester by offering free food and drinks to teachers and school staff. From now to the 19th, educators who are part of K-12 schools or universities can take advantage of the offer by signing up for Sonic’s Teachers’ Circle on their app. Each day of the week features a different free menu item that’s redeemable with any purchase made through the Sonic app or website. Additionally, Sonic contributes a portion of proceeds from drink sales year-round to public education via their Sonic Foundation and Limeades for Learning initiative.
