Staring on August 31, and only during breakfast hours, Chick-fil-A will offer a Chick-fil-A Chicken Biscuit, Egg White Grill, or Hash Brown Scramble Bowl for free via its Chick-fil-A One App for iOS or Android. That's tied with our mention from last September as the best deal we've seen for these breakfast foods from Chick-fil-A. Deal ends September 30.
