GOODLETTSVILLE, Tenn. — Striving to enhance its brick-and-mortar and digital offerings, Dollar General Corp. is adding fresh produce in stores while rolling out a shop-and-scan mobile app.

The chain this year plans to remodel 1,000 stores, two-fifths of which will become the “traditional-plus” format with 34 cooler doors to merchandise an expanded perishables assortment. Of the 750 traditional-plus stores planned by year-end, about a third will have produce, bringing to 450 the number of outlets offering fresh fruits and vegetables.

“Our cooler door expansion has proven to drive baskets and trips with our existing customer base, while also attracting new customers with an expanded offering,” said chief executive officer Todd Vasos.

“While it’s still early, prior-year traditional-plus remodels are yielding strong same-store sales results,” he noted. “The ability to offer produce, particularly in areas with limited grocery availability, represents an attractive growth opportunity for Dollar General in the years ahead.”

The new app allows customers to scan items while they shop and pay directly with their phones, making checkout faster and easier. “Not only does shop-and-scan help customers save time, it also makes staying on budget easier,” said Vasos, noting that shoppers can see the price of individual items along with a running total.

The chain sees “continued opportunity to improve engagement and build loyalty to further integration of our traditional and digital media mix,” he added.
