Sonic Drive-In is shaking up summer again! There once was a time when the popular fast-food restaurant offered discounted shakes every night, all summer long.
Unfortunately, they haven’t offered the sweet deal since 2019. However, this year, fans of the restaurant’s hand-spun shakes can enjoy sweet savings for a limited time.
