Discount grocers Dollar General and Dollar Tree had the biggest presence in the first edition of Supermarket News’ monthly store map with 87 combined store openings and seven closings.

Dollar General is backing away from the self-checkout trend in retail. The company is pulling out self-checkout stands in 300 stores that have the highest levels of shoplifting and merchandise losses.

Dollar General’s primary customers earn under $40,000 a year, and the chain has more than 20,000 stores, primarily in rural areas. Dollar General will still face pressure from tariffs, however.
