The deal lets you choose either two pieces of bone-in fried chicken or three chicken strips, plus two sides, and a buttermilk biscuit for $5.
For comparison, KFC's long-running $5 Fill Up offers a similar combination but with a chocolate chip cookie and a drink in lieu of one of the sides.
You can find the $5 Bonafide Big Box at participating Popeyes locations through Friday, March 31, 2017.
