McDonald’s is offering customers the chance to grab The Grand Big Mac for just £1.99 today across the UK.

The firm favourite consists of two 100% beef patties, a slice of cheese, lettuce, onion, pickles, and the delicious Big Mac sauce in a sesame topped bun - the same ingredients as a Big Mac, just bigger and better.

And with The Grand Big Mac promotion ending on March 23, there isn’t long left to get your hands on one before it is dropped from the menu.

The offer is for new and existing customers for one day only - customers will need to check when their local restaurant closes.

The offer is available exclusively on the My McDonald’s App. Simply download the app here to treat yourself to the latest offer.

The app will keep you up to date with the latest unmissable McDonald’s Monday deals each week. 

McDonald’s restaurants are now open for walk-in takeaway and customers can still order via the Drive-thru, McDelivery and Click & Serve using the My McDonald’s App.
