(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.
