As of 2014, Costco does not offer a one-day membership option. It does offer Executive Membership, Business Membership and Gold Star Membership for an annual fee. Members benefit by having a variety of high-quality, brand-name products available to them at the best possible prices both online and in store. In addition, members have access to a number of exclusive member services.
Based on individual needs, there are several membership options at Costco. The Gold Star Membership is designed for individuals and households buying products for personal use. The Business Membership is available to licensed businesses, non-profit organizations, government agencies, farmers and ranchers. For an additional annual fee, up to six additional cardholders may be added to a Business Membership. The Executive Membership is the highest level of membership at Costco. Executive members receive 2 percent cash back, with a maximum of $750 per year, on all purchases. They also receive travel benefits and discounts on select member services.
Costco memberships can be purchased online or at the membership counter of any open Costco warehouse. Members must be 18 years of age or older. The membership fee is fully refundable if an individual becomes a member and is not completely satisfied.
