McDonald’s is slashing 20% off its entire menu for one week - but only if you order through its app.
The discount is available from today (February 21) all the way through to this Sunday (February 27).
You'll be able to use the 20% discount once a day, and the offer will appear in the “offers” section of the app.
To get the money off, you’ll need to click on the deal and then add it to your order. The money off will then automatically be applied to your bill.
You can get 20% off both collection and delivery orders, but only if your home delivery order is made through the My McDonald’s app.
But keep in mind that when you order food to be delivered, you’ll pay an extra charge on top of your order.
This is typically around £3.99 but can vary depending on where you live in the UK and how far away from a McDonald’s you are.
The 20% off won’t be applied to home delivery orders paid for on Uber Eats or Just Eat.
McDonald’s says everything on the menu is included in its 20% off deal - from your breakfast McMuffin to a classic Big Mac.
If you fancy a Big Mac, this will normally set you back £3.49 - so with the 20% discount, you can get it for £2.80 instead.
The latest Maccies offer comes after it devastated fans by removing its new Chicken Big Mac burger just days after its launch.
The limited edition burger was only launched in the UK on February 2 for a six-week run - but was pulled on February 11 due to “incredible” demand.
McDonald’s hasn’t said when the popular burger will be back.
The fast food chain tweeted: “Well, that escalated quickly. Your love for the limited edition Chicken Big Mac knew no bounds and it’s sold out almost everywhere.
“Thank you for lovin’ it even more than we thought you would, it’ll be back soon.”
The new Chicken Big Mac is pretty much the same as a regular Big Mac with the special sauce, but it has chicken patties instead of beef burgers.
It costs £4.09 for just the sandwich, or £5.59 for a medium meal with chips and a drink - you can go large for £5.99.
Is McDonald's better than KFC? Or is Burger King your go-to takeaway? Let us know in the comments below.
McDonald's has around 1,300 restaurants in the UK.
Other new items that have been introduced on its menu for a six-week run include the return of the Double Big Mac and Mozzarella Dippers.
No other menu items have been temporarily removed.
McDonald's customers were left disappointed after the Chicken Legend was removed from the menu in October due to supply issues.
But the iconic burger - which contains chicken breast meat, with lettuce and mayo in toasted roll - was confirmed for a return on February 2.
