This Wednesday is National Cheeseburger Day in the United States: Here are some deals to enjoy

() – Wednesday is National Cheeseburger Day in the United States, and some of the largest chains are offering some much-needed discounts across the country amid consumer complaints about the price increase.

McDonald’s, the largest company, is selling double cheeseburgers for 50 cents when you order them on its app, about 45 cents more than the chain’s original burger cost in 1948. It’s part of a series of deals by the company to revive sales, including the recent extension of its popular $5 meal through December.

Fast food has been a business with low profit margins and poor customer loyalty. Chains have been introducing big giveaways, usually tied to their mobile apps, to help boost business and develop more repeat customers.

And McDonald’s isn’t the only burger chain offering deals. Through Sept. 22, Wendy’s is offering a junior bacon cheeseburger for just 1 cent, as long as you buy something else from its app. Additionally, Burger King is giving away a cheeseburger whenever you buy something worth at least $1 through its app.

Smaller chains are also offering similar deals. Jack in the Box is giving away a free Jumbo Jack cheeseburger with a $1 purchase on its app, and Carl’s Jr.’s app is offering a half-price double cheeseburger. White Castle is offering a buy-one-cheeseburger deal on the app with the code “SAYCHEESE.”

Smashburger, which just unveiled a new logo and menu, is offering $5 cheeseburgers (which normally cost upwards of $7) with the code “BURGERDAY” on its app or in-store, as well as offering a vegetarian alternative. It’s also giving a “bounce-back coupon” to anyone who orders the deal so customers can come back and get 50% off any burger or sandwich on a future visit.

McDonald’s overpriced burgers have become a focus of criticism and a symbol of high fast-food prices. Joe Erlinger, president of McDonald’s U.S., wrote in an open letter posted on the company’s website in May that franchisees should avoid one-time price increases that would damage the company’s reputation. He noted that prices have not risen as much as people think.

Still, customers have turned away from fast-food chains in favor of casual dining chains like Applebee’s and Chili’s, which many customers believe offer better value.

That’s why offers are crucial to attract customers.
