Dollar General has plans to open six stores in North Dakota, US, later this year.
The company also opened a new store in Hankinson, North Dakota, last week.
Dollar General offered the first 100 customers complimentary gift cards and totes filled with product samples to celebrate the opening.
Dollar General chief executive officer Todd Vasos said: "This is an important milestone for Dollar General as we expand into our 44th state and build our presence in the upper Midwest.
“We look forward to serving additional communities with value and convenience as we grow our footprint throughout the state and welcoming new North Dakotan employees to the Dollar General family.”
Dollar General claimed that it has been providing convenience, as well as value to its customers by offering a selection of items such as food, apparel, paper products, and health and beauty items.
The company offers more than 80% of items at $5 or less.
Dollar General plans to identify additional areas for new store growth in the state. These stores will be supported by items from one of its newest distribution centres in Janesville, Wisconsin.
Dollar General most recently expanded from stores in 40 states to 43 states with the opening of stores in Maine, Rhode Island and Oregon in March 2015.
It has 13,200 retail outlets and 120,000 employees.
