Chick-fil-A giving away free chicken nuggets with mobile app

Chick-fil-A is giving away free chicken nuggets, but it comes with a catch.

All customers who download the Chick-fil-A One mobile app can score a free 8-piece order of chicken nuggets.

You can redeem the offer only once through September 29.

The Atlanta-based fast-food chain said the reward system is designed for its most loyal customers.

"Our membership program is just as much about what you give as what you get," said White. "Members will earn points with ever purchase that can be used to redeem available rewards of their choice like an Icedream® or Chick-fil-A Chicken Sandwich, and we're excited to offer Chick-fil-A One Silver and Chick-fil-A One Red Members a way to spread a little kindness too."
