Timing is everything when it comes to scoring the best deals with Sonic promo codes. One of the smartest ways to save is by using these codes during Sonic’s daily Happy Hour, when drinks and slushes are already half-price. Pairing a promo code with these specials can double your savings. Seasonal promotions, like summer and back-to-school events, also bring exclusive codes that unlock extra discounts on meals and combos. For frequent deals, keep an eye on the Sonic app or subscribe to text alerts—they often release limited-time offers during holidays or weekends. Planning your visit around these high-value times ensures you enjoy your favorite meals without overspending.
