Costco Wholesale is a nationwide warehouse-style retailer that sells items individually and in bulk. To shop at Costco, you must purchase a business or personal membership and present your card before entering the store. Costco Wholesale offers three ways to apply for a membership.

The quickest way to apply for a membership is to visit a Costco warehouse location. The process consists of providing personal and contact information to a membership representative, accepting Costco's membership terms and conditions and paying the current membership fee. Once you do this, you'll receive a membership card and a copy of the terms and conditions, which allows you to start shopping.
