McDonald's offered a special promotion on September 18, 2025, for National Cheeseburger Day, where customers could get a Double Cheeseburger for just 50 cents by ordering through the McDonald's app, limited to one per customer at participating locations. Outside of this promotion, the regular price for a Double Cheeseburger in 2025 is around $4.19 as part of a "Buy One, Add One for $1" meal deal, or approximately $3.99-$4.39 at other times without promotions. This 50-cent deal was a one-day special to drive digital engagement and celebrate the holiday.
