The コストコ公式アプリ is a lifestyle app developed by Costco Wholesale Corporation for iPhone users. It offers a convenient way to shop online at Costco and enjoy the benefits of being a Costco member.

With this app, you can easily browse and purchase products from Costco's online store. The app also features a wishlist function, allowing you to save items for future reference. In addition, it offers a digital membership card that can be used at warehouse stores, eliminating the need to carry a physical card.

New and existing Costco members can use the app to sign up for or renew their membership. The app also provides access to exclusive discounts and offers available both online and at warehouse stores. You can view your purchase history and track your orders online, making it easy to keep track of your shopping activities.

Furthermore, the app keeps you informed about upcoming events at warehouse stores, ensuring that you don't miss out on any exciting promotions or special offers.

The コストコ公式アプリ aims to continuously enhance its features to provide even more convenience to its members. Please note that to enjoy the full benefits of online shopping and exclusive features for Costco members, a Costco membership is required. You can purchase a membership through the app, website, or at a warehouse store. While limited functionality is available for guest users, becoming a member unlocks the app's full potential.
