They don't own the retail locations. They usually lease. If a location underperforms.. they can yank up shop and shut the doors with little issue. That is part of what doomed Fred's. They were rooted in their locations.I don't understand how Dollar General stays in business. I live in area with a populatuon of probably 30,000 people and there atleast 12 DG stores within 20-25 minutes of my house. Inventory management at most of them seems non-existent. There are more products in boxes on the floor and on carts there on the shelves. Nobody at the checkout counter - you have to squeeze and squeak a rubber chicken dog toy to get someone to come check you out.
And the stores, in rural areas, are usually between a section of population and larger box stores where they don't exactly blow the doors off of customer service either. And you can usually get away with poor service if the price is right on items.
Basically Dollar General runs on a modified foreign born convenience store owner model. Except dollar general doesn't pack up the store in the early morning hour and leave a large tax and fuel supplier bill unpaid when they vanish.
