You can only get one 50‑cent cheeseburger in the current main promo that people are talking about.

Quick Scoop: What’s Going On?

  • The well-known 50‑cent cheeseburger deal is a limited-time National Cheeseburger Day promotion at McDonald’s in 2025.
  • It applies to the Double Cheeseburger (not every burger), and it’s only on that specific day.
  • The catch: the offer is limited to one Double Cheeseburger per customer/account via the app at participating locations.

So if your question is literally “how many 50 cent cheeseburgers can I get?” under that promo, the answer is: one per person (per app account) on the promo day , unless a specific restaurant runs a different local deal.

Mini breakdown

1. Why only one?

  • The promo is meant as a teaser deal to get you into the app and the store, not to let people buy 20 burgers for pocket change.
  • Terms say one redemption per customer, which is standard for app-based fast‑food coupons now.

2. Could there be other 50‑cent cheeseburgers?

  • Historically, some places and eras really did have super‑cheap burgers (like under a dollar and even well below that decades ago).
  • In modern times, 50‑cent cheeseburgers are usually special event or holiday promos , not everyday menu prices.

3. What if you have more money?

If you’re thinking, “I’ve got $10, how many 50‑cent cheeseburgers can I get?”:

  • Under this national app promo: still 1 , because of the hard limit.
  • You can, of course, buy regular‑priced cheeseburgers after that, but they won’t be 50 cents.

4. Forum-style take

On forums and social media, most of the “how many can I get?” jokes are people fantasizing about stacking dozens of 50‑cent burgers, followed by someone pointing out the fine print: “One per customer, dude.”

TL;DR: Under the current big 50‑cent cheeseburger (Double Cheeseburger) deal, you get one cheap burger per person via the app on the promo day; after that, it’s back to normal pricing.
