What is the Difference between Costco executive gold star and Costco business membership?

Costco's Executive Gold Star Membership offers individual members enhanced benefits, including 2% cashback on eligible purchases and access to special discounts, while the standard Gold Star membership provides basic access to Costco stores and services. In contrast, the Business Membership is designed for businesses and allows multiple cardholders under one account, along with the ability to purchase for resale. Business members can also access additional services like cash credit for returns. Both memberships provide access to Costco's warehouse stores and products, but they cater to different types of customers.
