Question: when are sonic drinks half price?
Answer: Sonic Drive-In is “shaking up” late nights again with one of its most popular deals, Sonic Nights. This spring and summer, make a sweet stop to hit your sweet spot for ice cream at a bargain price. The burger chain's daily half-price Happy Hour on drinks and slushes from 2 p.m. to 4 p.m. does not include shakes.
