The stores got 3 areas, and each is like a different store.
The main floor is just expansive clothing for the most part, along with stuff they keep behind the counter (knives, etc). I don't shop there.
The top floor is like an EMS or REI. Only better. They have a lot of camping gear, but have things other stores wouldn't, like a great array of cast-iron cooking tools (pots, pans, dutch ovens, hot trays, and more).
The basement is their surplus floor, and you can get fairly inexpensive cloths there. Because they are mostly military surplus, they are usually really durable and/or utilitarian.
The employies are general very helpful, though one or two are annoying.
