This Costco store, like all of this chain, is a warehouse of grocery, bakery, books and clothing items. It also carries some gifts, exercise equipment, furniture, music, and movies. For a yearly membership fee, you can save quite a bit of money and buy items in bulk . The Mountain View store features a bakery where you can get fresh breads and special order cakes. This is a great place, but on the weekends the store can be very crowded and the checkout lines are long.
