Dollar General introduced its DG Fresh program in 2019 and has continued to expand its fruit and vegetable offerings since then. Dollar Tree piloted fresh produce a few years later, and has been aggressively growing its frozen and refrigerated options in recent years. In its most recent earnings call, Dollar Tree said its frozen and refrigerated product ranges -- which include fresh produce -- are now available in nearly 5,600 stores, which is about a third of the total number of Dollar Tree and Family Dollar stores combined.
