7-Eleven Shifts Focus to Healthier Food Options

Convenience stores have typically been among the most nimble of retailers. In the 1980s, they added Pac-Man arcade games as a way to keep customers in stores longer and to buy more merchandise. They installed A.T.M.’s a decade later, taking a slice of the transaction fees. More recently, they built refrigerated dairy cases, with milk, eggs, cheese and other staples.
But just as they have taken business from traditional supermarkets, convenience stores have faced increased competition from the likes of Dunkin’ Donuts and Starbucks, which offer a basic menu of fresh foods for consumers on the go.
At the same time, a major profit driver for convenience stores — cigarettes — has been in steady decline over the last decade as the rate of smoking has dropped in the United States.
