- Many coupon sites list codes that nobody has tested.
- Real fast food deals usually live in the official app, not on random websites.
- Never share card details or passwords to get a coupon.
In this guide
Search for almost any fast food promo code and you’ll get pages of them promising 20%, 50%, even 70% off. Try a few and you’ll notice most don’t do anything. There’s a reason for that, and once you know the signs, it takes seconds to tell a dead code, or a scam, from a real deal.
Why coupon sites list codes that don’t work
Many coupon websites earn money from ads and clicks, not from codes that work. Some collect codes automatically from other sites, some keep expired codes online because they still bring in visitors, and some publish codes that were never real. Labels such as “verified” or “official” mean little if the page doesn’t say who checked the code and when.
Warning signs of a fake promo code
- The discount is too good. A storewide 50% off code for a fast food chain is very unusual.
- There’s no date. An honest list says when each code was last checked.
- The dates don’t match. A page titled with this month that mentions offers from years ago is usually recycled.
- Generic codes everywhere. Codes like SAVE20 or WELCOME10 listed for every brand are often guesses.
- “Show code” buttons that open other websites or pop-ups before revealing anything.
Coupon scams to avoid
Fake codes waste your time. Coupon scams can cost you money or personal data. Be careful with any deal that:
- asks for your card number, bank login or passwords to “activate” a coupon;
- asks you to pay with gift cards (the US Federal Trade Commission warns that anyone who demands payment by gift card is a scammer);
- promises free food for a year in exchange for sharing a post or completing surveys on unrelated websites;
- arrives by text message with a link to a website that isn’t the brand’s own.
Already typed your card details into a site like that? Call your bank today and ask them to block the card.
Where real fast food deals come from
- The official app. For Burger King, most deals are in the Offers section of the BK app.
- Loyalty programs such as Royal Perks, which turn purchases into free food.
- Your receipt. Survey offers printed on receipts are real and easy to claim.
- Official social media accounts and emails you’ve signed up for.
- Delivery apps, which run their own promotions inside the app.
How to test a code safely
- Only enter codes in the official app or website, or inside a delivery app you already use.
- Add the code before paying and check that the total drops.
- If it doesn’t work, remove it. Never hand over extra personal information to make a code work.
Our approach
On Burger Deal Finder, every code we list links to the site where it was published, so you can see exactly where it came from, and codes we’ve tried ourselves are marked as tested. When there’s no code worth listing, we say so and point you to the app offers instead. More on our About page.
