Sunday, September 20 is National Pepperoni Pizza Day, and Kolache Factory is celebrating with one of its most popular kolache flavors.

On that day, Kolache Factory locations will have a “Buy 3 and Get 3 Free” offer for one day only on Sunday, September 20. This deal is good on any kolache except Polish varieties, but the company says that it hopes customers will give its pizza kolaches a try.

Guests can find the coupon on any of the company’s social media sites, including Facebook, Instagram and Twitter. They can print off the coupon or simply show it to the cashier on a phone. The offer is valid in-store or curbside.

“One of the best things about our Czech-inspired pastry kolaches is that they can be made to satisfy any craving you might have,” says Kolache Factory chief operating officer Dawn Nielsen. “Our pepperoni pizza kolache is a pepperoni lovers dream with tons of pepperoni, mozzarella cheese and marinara sauce wrapped in our sweet pastry roll!”
