It has a vast selection of items that you would except any typical grocery store to have, including fresh produce, generic and name-brand dry goods, frozen items and household supplies. Weekly specials are available for customers with a bonus card from the store. Since this location sits on the Maryland-D.C. border, a two-hour parking lot is enforced for paying customers.
