To join Costco, one must apply at the official Costco website or visit a local Costco store. As of September 2014, there is a membership fee to shop at Costco.
Costco is a wholesale warehouse that sells items in bulk at a lower cost than retail stores. Costco sells groceries, electronics, furniture, jewelry, office products and many other items. Costco offers discounts on travel, prescriptions and photos. Costco also offers discounts on services such as identity protection, online investing and water delivery. Not all services and offers are available in all states, and information for the available services can be found on the Costco website.
