Jump to Section
National Cheeseburger Day lands on Friday, September 18, and the burger chains are going all out this year.
View Today’s Best Deals
We rounded up 13 of the best deals across the country, starting with the flat-out freebies, then the buy one get ones, then the cheap eats worth building a lunch run around.
Most of these require the chain's app or a rewards account, so download ahead of time and save yourself the scramble at the counter.
Free Burgers
McDonald's is giving rewards members a free Double Cheeseburger with any $1 purchase on September 18. You have to order through the McDonald's app and opt into MyMcDonald's Rewards, and it is limited to one per person.
Jack in the Box is matching that energy with a free Jr. Cheeseburger when you spend $1 or more in the app. Limit one redemption.
Dairy Queen started early on this one. Rewards members get a free single Original Cheeseburger Signature Stackburger with any app or online order of $1 or more, and the deal runs September 14 through 18, so you do not have to wait until Friday.
Whataburger is handing rewards members a free Bacon & Cheese Whataburger Jr. with the purchase of medium fries or onion rings. Redeem it and you are also entered for a chance to win free Whataburger for a year.
Buy One, Get One
Five Guys rarely runs promo codes, which makes this one a standout. Use code BOGOBURGER when you order online September 16 through 18 and your second burger is free. Online only, so it will not work if you walk up and order in store.
White Castle has a BOGO Cheese Sliders deal for Craver Nation Rewards members. Use code BOGOCHEESE at online checkout.
Buffalo Wild Wings is in the mix too. Buy one regular-priced cheeseburger on September 18 and get a second of equal or lesser value free at participating locations. It excludes the lunch combo and kids menu burgers, and it is a great option if you are splitting dinner with someone.
Burger King is running a full week of Royal Perks deals from September 14 to 20. Friday is the headliner with a free Bacon Cheeseburger on a $3 minimum purchase, but there is a freebie every single day: a free Rodeo Burger on the 14th, BOGO Whopper Jr. on the 15th, free Croissan'wich on the 16th, free Hamburger on the 17th, free 4-piece Nuggets on the 19th, and a free Original Chicken Sandwich on the 20th. Everything except the Sept. 15 BOGO needs a $3 minimum, redeemed through the app or website.
Cheap Eats
Smashburger is letting rewards members grab any single burger for $1 with an app order. New and existing members qualify.
Sonic has $1.99 Jr. Double Cheeseburgers when you order in the app.
Shake Shack is offering a ShackBurger or Cheeseburger for $5 with code BURGERDAY.
Wayback Burgers has $3.50 single cheeseburgers, good in-restaurant, online, and through the app. Limit two per person.
Carl's Jr. rounds it out with a half-priced Western Bacon Cheeseburger, available in Single, Double, Triple, or Spicy, when you buy any large beverage. Rewards members only.
Bottom Line
Whether you are feeding the whole family or just skipping the stove on a Friday night, this is the week to cash in. Download the apps you need now, and remember that participation and pricing can vary by location, so it is worth confirming your local spot is in on the deal before you head out.
