Tomorrow is National Waffle Day and Casey’s is celebrating. The Iowa-based retailer is bringing back its LTO Ultimate Waffle Breakfast Sandwich starting September 4. Casey’s said the sandwich “features a sweet and savory combination of crisp bacon, hearty sausage and fluffy eggs between warm maple waffles.”

Casey’s rewards members can unlock the sandwich early starting tomorrow, August 24. The $1.99 sandwich offer will be available in the Casey’s app from August 24-28, redeemable until September 15. The sandwich will be available across all stores in Casey’s 17-state footprint.

Casey’s is known for its pizza, but in addition to the Ultimate Waffle Breakfast Sandwich LTO and other breakfast options, it also introduced an all-new sandwich line up earlier this year. The menu items included crispy chicken sandwiches with a spicy option, a quarter-pound Angus burger and a breaded pork sandwich.

Last month, Casey’s acquired CEFCO Convenience stores in a $1.1 billion deal. The all-cash transaction included 198 stores and will increase Casey’s footprint to nearly 2,900 stores. The acquisition will bring 148 additional stores to Texas, which Casey’s describes as a “highly strategic market” for the retailer, as well as 50 stores in Alabama, Florida and Mississippi.
