In honor of National Cheeseburger Day on Monday, September 18, here is a list of restaurants celebrating this holiday. Words to the wise, some deals won’t work through third-party apps. So DoorDash, UberEats, Grubhub, Postmates, and other delivery apps can leave the chat.

Burger King

This is exclusive to members of their rewards program, RoyalPerks. But that could be fixed with a quick sign-up. The week-long deal makes sure customers have it their way. Offers vary by location, so be sure to pinpoint your location and double/triple-check the app and website for deals to the nearest Burger King.

Monday, September 18: Free cheeseburger with any purchase of $1 more

Tuesday, September 19: Free Whopper Jr. with any purchase of $1 more

Wednesday, September 20: $3 Whoppers

Thursday, September 21: BOGO Whoppers

Friday, September 22: Free onion rings with any purchase of $3 more

Saturday, September 23: $22 Family bundle

Sunday, September 24: Earn double crown points on all purchases

With 102 restaurants across the United States and receiving positive feedback from using the deal previously, BurgerFi is looking to be the face of National Cheeseburger Day.
