Sonic Drive-In is one of the easiest fast food chains to save money at, but most people never use the deals that are available every single day. This page collects every working Sonic coupon and promo code for 2026 in one place, from the daily Happy Hour that cuts all drinks in half to app-only offers, free sides, and buy-one-get-one burger deals. Copy any code below, or just show up at the right time for the automatic deals. Everything here is checked and refreshed every week.

Off Drinks
Every day from 2 PM to 4 PM, every drink and every slush is half price. It applies automatically at the stall, in the drive-thru and in the app, and there is nothing to enter and nothing to show. This is the single biggest saving at Sonic and the only one that needs no account.
Every day, 2 to 4 PM
APP
Only
Sonic runs its discounts through the app rather than through codes: a free item for joining, offers tied to your account, and deals that change week to week. Which ones you see depends on your account and your location, so the app is the only place that can tell you what is live today.
Offers rotate, check the app

Birthday
Add your date of birth to your Sonic Rewards account and a birthday reward is added to it on the day. It arrives in the app as a redeemable offer, so there is no code and nothing to print.
On your birthday, via the app
Standing specials
These are not promotions and they do not expire. They are how Sonic prices four parts of its menu, which makes them the only specials anyone can promise will still be there when you arrive.
Every drink and every slush, seven days a week. It puts 61 more of them under $1.99 for those two hours.
Mini drinks, slushes and cups of ice, plus a handful of things you can actually eat. No window, no app, no code.
An entree, a side and a drink from $4.69, which is less than the side and drink cost separately.
A cheeseburger, chicken bites, medium tots or fries and a drink at one flat price. Sonic's only standing combo.
Day by day
Not as a national price, and it is worth knowing why before you drive over on a Tuesday. Sonic's store-level pricing carries one price per item per location. There is no weekday column in it, for any item, at any of the 3,357 drive-ins in the data.
That does not make the specials people remember imaginary. Sonic drive-ins are independently owned and run their own promotions, and the app pushes offers that change week to week and differ by account. Both are real. Neither is something a national price guide can quote you, and any page printing a Tuesday burger price is quoting one store or quoting nothing.
The one genuinely everyday exception is Happy Hour, and it is everyday in the literal sense: 2 to 4 PM on all seven days rather than on a particular one. That makes it the closest thing Sonic has to a daily special, and the only one that needs no app and no code.
Milkshake deals. Real, and they belong to the app in the evening rather than to the afternoon. Shakes and Blasts sit outside Happy Hour entirely, so ordering one at 3 PM gets you no discount at all.
Hamburger and burger specials. Not on the national price list. Burgers have one price per location, so a burger special is either the app or that particular drive-in running its own promotion.
The brown bag special, 2 for $5, corn dog deals. We are not going to price these. They are limited-time or regional promotions with nothing behind them in Sonic's store-level data, so any figure printed for them would be a guess with a decimal point on it. The app and your own drive-in are the only two places that can say.
Simple Steps
Order a drink or a slush between 2 and 4 PM. The halved price is what comes up on the screen. There is no code, no account and nothing to show the carhop.
Open the Sonic app, add your items, and tap the offer before you check out. Offers are attached to your account rather than to a code, so there is no promo field to paste into.
Whichever route you took, the discount should already be in the total. If it is not, it is worth asking at the stall before you drive off rather than after.
Good to Know
Not public ones. Sonic's discounts arrive two ways, and neither is a code you can type: Happy Hour, which is automatic and needs nothing, and the app, where offers are attached to your account and rotate. Every Sonic promo code circulating on coupon sites is either expired or was never real, which is why this page lists none.
The ones that are running today are the ones that run every day, because Sonic's standing specials are pricing rather than promotions: half price drinks and slushes from 2 to 4 PM, 41 items already at $1.99 or less, Wacky Packs from $4.69, and the Big Deal Meal. Anything beyond that is in the app, tied to your account, and changes week to week.
Not nationally. Sonic's store-level pricing holds one price per item per location, with no weekday variants anywhere in it across 3,357 drive-ins. A weekday special you have seen is a local promotion or an app offer, both of which are real and neither of which a national price guide can quote.
Happy Hour, by a distance, and it is not close. Half off every drink and slush for two hours a day, applied automatically, no account needed. It drops 61 more products under $1.99 while it runs, including a Route 44, which is the most ounces per dollar anywhere on the menu.
Happy Hour needs nothing at all: order a drink between 2 and 4 PM and the halved price is what comes up. App offers are tapped to apply in the app before you check out. Neither involves typing anything into a promo field, which is the part most coupon pages get wrong.
The Happy Hour window is, but the price underneath it is not. Drive-ins are independently owned, so half of one store's Route 44 is not half of another's. The figures on this site are medians across thousands of locations, so your local price will sit close rather than exactly on them.
Sometimes, through the app, and never as a code. Those offers are account-specific and short-lived, so nobody can publish a list of them that stays true for a week. If a page is showing you a BOGO burger code, it is showing you something that does not work.
