Costco could almost be its own city. In addition to having one of the most affordable food courts around, this wholesale superstore also boasts a gas station, hearing aids office, pharmacy and optician. The wholesale warehouse sells just about everything a large family or small business owner would need, including bulk-size foods, furniture, shoes, clothes, household items, and flowers, among much more. Shoppers are encouraged to taste food samples to before committing to bulk purchases.
