Trick will get you and a friend a Burger King burger for £1

Burger King has launched its first-ever in-app refer-a-friend-scheme which means you and a friend can both get a Chicken Royale or Vegan Royale for GBP1. There is no limit to the number of Chicken Royale burgers you can claim but the offer is only available on the Burger King app until January 31. The deal is activated when you refer a friend and get them to download the app.

The offer, called Burger King Friends Forever, is available on Click & Collect, Kiosk & Front Counter in participating BK restaurants only.

Offer is not available on BK Delivery or in Burger King motorway service locations, airports, train stations and holiday parks.

Your friend will need to download the app on your referral and place an order of more than GBP10 to activate the deal.
