US Burger King offers McDonald's Whopper burger for only one cent

In their rivalry with the popular fast food outlets, Burger King in the US came up with an original way to get customers to download its BK app. If anyone is within 600 ft of a McDonald’s outlet, they can then unlock a deal giving them a Whopper burger for only one cent. The app then gives them directions to their nearest Burger King to collect their one cent burger, cutting out McDonald’s completely. The deal is running until 12 December and can only be used once.
