A great warehouse shopping mecca! Costco is fairly new to the South Saint Louis area, and it really has been a great addition. I think Costco is better than Sam's club, as they have a nice selection of items and their prices are always great. Their food selections are especially good here. They always have a lot of books and movies for sale, as well as other furniture and appliances. I definitely recommend going here for a day to see if it is worth it for you to buy a membership, which is $45.
