Penny Whoppers at Burger King
Get a practically free Whopper at Burger King by going to McDonald’s. Wait, what? Anyone who opens the Burger King mobile app within 600 feet of a McDonald’s restaurant will be able to order a Whopper sandwich for a penny through Dec. 12.
The app will be able to tell whether users are in one of the geofenced areas around 14,000 McDonald’s restaurants nationwide. Then, the app will magically unlock the penny promo and detour you to the closest Burger King for pick up.
