(NEXSTAR) – A number of national burger chains are offering heavily discounted cheeseburgers in honor of National Cheeseburger Day on Wednesday, albeit with a common, fairly obvious caveat.

Yep, you guessed it. With few exceptions, you’ll probably have to sign up for some sort of loyalty program and order through an app.

Knowing this, there’s really only one question you need to ask yourself: Is a discounted cheeseburger really worth the time and potential hassle of signing up for yet another loyalty program? Well, that’s for you to figure out. All we can do is relay any information you might need to make a well-informed decision.

Sit with that for a bit while you peruse Wednesday’s juiciest deals below:

Buffalo Wild Wings

Members who belong to the Buffalo Wild Wings loyalty program — known as the Blazin’ Rewards program — can get a free cheeseburger when they order a regularly-priced cheeseburger of equal or greater value. Customers can also provide their server with the phone number connected to their Blazin’ Rewards account when dining in.

Burger King

Customers belonging to BK’s Royal Perks rewards program can add a free cheeseburger to their order when making a separate purchase of $1 or more on the Burger King app.

BurgerFi

Dine-in guests who buy a Freestyle Coca-Cola product on Sept. 18 can purchase a BurgerFi cheeseburger for $4.

Carl’s Jr.

Carl’s Jr. is offering half-priced double cheeseburgers purchased through the Carl’s Jr. app on Sept. 18.
