Shake Shack Targets Chick-fil-A with Sunday Chicken Sandwich Promotion

The fast-food chain's offer highlights antibiotic-free options and takes advantage of Chick-fil-A's Sunday closures.

Shake Shack launches a promotional offer for a free chicken sandwich every Sunday in April with a $10 minimum purchase, using the code CHICKENSUNDAY.
The promotion is seen as a direct jab at Chick-fil-A, highlighting Shake Shack's antibiotic-free chicken and availability on Sundays, a day when Chick-fil-A is closed.
Shake Shack's campaign uses the tagline 'Eat More Antibiotic-Free Chicken,' in contrast to Chick-fil-A's recent shift from a 'no antibiotics ever' policy to one less strict.
Despite the competitive promotion, Chick-fil-A boasts significantly higher average revenue per location compared to Shake Shack.
The move sparks discussions on the rivalry between the two chains, with Shake Shack's effort to compete with Chick-fil-A's dominance in the chicken sandwich market.
