DES MOINES, Iowa — Burger King Corp., in a move that could ignite a fast-food discounting war, plans to test a $1 double cheeseburger that would challenge one of McDonald’s Corp.’s best-selling items. “It is our belief that the dollar double cheeseburger is the most powerful weapon our competitor has to continue their growth and steal disproportionate share from the category,” Burger King’s chief marketing officer said in a note disclosing the upcoming test, which was e-mailed recently to employees and franchisees. The nation’s No. 2 hamburger chain, Burger King said it will feature a larger double cheeseburger than McDonald’s at a heavily discounted rate in three unnamed U.S. markets early next year. Burger King restaurants now typically charge well over $2 for that sandwich.
