Sonic Coupon & Deals

Just use the app. Seriously, drinks and slushes are half price all day on it instead of waiting for the standard happy hour. Half-price cheeseburgers pop up on Tuesday nights after 5 PM, too. Check your specific location first before pulling in, though, because local franchises constantly opt out of corporate promos.

The app won't let you cancel once the kitchen ticket prints, which happens almost instantly. Don't bother emailing app support. Call that specific location's number immediately and give them your name. If you're already pulled into a stall, hit the red button and tell the carhop to void it.

Sonic doesn’t do referral codes at all. Don't waste time hunting for one. Just download their app instead; you automatically get half-price drinks and slushes all day when ordering ahead, not just during the 2–4 PM stall happy hour. Check the “Rewards” tab too; they usually drop half-price burger promos on Tuesdays.

Skip ordering at the red button. Always order ahead in the Sonic app. You automatically get half-price drinks and slushes all day instead of waiting for happy hour. The tots and burgers are fine, but Tuesday nights have half-off burgers in the app's rewards tab. Don't pay full menu price.
