A third-generation convenience-store chain and working dairy, Byrne Dairy operates sites throughout upstate New York. Byrne Dairy offers a “membership card” linked to a checking account that allows users to save as much as 10 cents on every gallon of gasoline purchased. Price signs show gas prices for both members and nonmembers.

The company drives traffic from the pump into the store with broad foodservice offerings, including Byrne Dairy & Deli in some locations. A handful of stores offer growler filling stations featuring craft beer, and locations also spotlight the company’s dairy products, including ice cream and milk.
