Burger King is offering 1-cent Whoppers ‘at’ McDonald’s
MIAMI -- Burger King is using its competitor's own restaurants as part of a devious new promotion. Its "Whopper Detour" deal is giving customers Whoppers for one cent. But, and here comes the sneaky part, customers have to be using the Burger King app to order -- and be at a McDonald's.
