The soup is offered in medium (8-ounce) and large (16-ounce) sizes at $3.65 and $5.99 respectively.
Chicken Tortilla Soup was first introduced to the Chick-fil-A menu in January of last year. The price has gone up a fair bit since then and it looks like northern beans have been removed from the ingredients.
Chick-fil-A's Chicken Tortilla Soup will be available through March 31, 2013.
