Let's do the math! A Frosted Lemonade at Chick Fil A costs $4.49 before tax, as of June 2022. I bought a half gallon of vanilla ice cream for $4.39 and a 52 oz bottle of Simply Lemonade for $2.58. I was able to make 4 servings for $6.92. Four frosted lemonades at Chick Fil A would have cost $17.96 + tax. So I would say yes!
