Sam's Club is what it is. Members only, large quantities, cheaper than normal prices. It does offer quite a selection of items and variety within a category (ex. lots of different coffees, ketchup, etc.). The bakery is actually surprisingly good, especially the chocolate chip cookies. Definitely a good place to stock up on meat. They butcher a lot of it in-house, and it's significantly cheaper than some of the local grocery stores. Beware of over-purchasing while you're there. For some reason when you're in this store, the idea of buying 1,000 rolls of toilet paper seems totally normal and reasonable.
Very clean, with friendly and helpful staff!
