TERMS AND CONDITIONS OF USE

Last Updated October 7, 2026
PLEASE READ THESE TERMS AND CONDITIONS OF USE CAREFULLY

These terms and conditions of use (“Site Terms”) are an agreement between Costco Wholesale Corporation, together with its subsidiaries and affiliates (“Costco,” “we,” “us”) and you. The Site Terms apply to your access and use of (i) our websites, including costco.com, costcobusinessdelivery.com, costcotravel.com, costcoconnection.com and other Internet sites, and social media sites operated by or for Costco (collectively, the “Sites”), (ii) mobile applications that may be downloaded to your smartphone or tablet (collectively, the “Apps”), (iii) online services accessible through the Sites and Apps (collectively with the Sites and Apps, the “Services”), and (iv) products made available for purchase through the Site and the App (the “Products”). By using the Services, you agree to be bound by the Site Terms. If you do not agree to be bound by the Site Terms each time you use the Services or you do not have the authority to agree to or accept these Site Terms, you may not use the Services.

The Site Terms are separated into two parts. Part One applies to all uses of the Services, and Part Two applies when you purchase Products through the Services.

Part 1 Terms of Use for the Services

We may indicate that additional policies and terms (“Supplemental Terms”) apply to use of specific Products or Services. All applicable Supplemental Terms become part of the Site Terms. In the event of any conflict between these Site Terms and the Supplemental Terms, the Supplemental Terms govern with respect to the applicable Products or Services. Please refer to and review all additional Supplemental Terms.

The Site Terms apply exclusively to your access to, and use of, the Services and do not alter in any way the terms or conditions of any other agreement you may have with Costco.

Costco has adopted a privacy policy that you should refer to in order to understand how we collect, use and share information. To learn about Costco's privacy practices, please refer to the Your Privacy Rights page.

2. Modification of Site Terms

Costco reserves the right to amend these Site Terms in our sole discretion from time to time and only Costco has the right to do so. If the Site Terms are changed, we will provide you with notice of such changes, such as by sending an email or updating the date at the top of these Site Terms. Unless we say otherwise, any changes or modification will be effective upon posting of the revised Site Terms. If you do not agree to the amended Site Terms, you must immediately stop using our Services. Your continued use of the Services constitutes your acceptance of the amended Site Terms.

3. United States Usage

The Services are operated by a U.S. entity and are governed by the state and federal laws of the United States. The laws of your jurisdiction may be more or less strict than the laws that apply to the Services. If you access the Services from outside the United States, you do so at your own risk and are responsible for compliance with the laws of your jurisdiction.

You may not use the Services if you are (a) located in, or a resident or a national of, any country or region subject to a U.S. government embargo or other restriction, or that has been designated by the U.S. government as a “terrorist supporting” country or region or (b) the subject of U.S. sanctions or of sanctions consistent with U.S. law imposed by the government of the country where you are accessing the Services. You are responsible for compliance with all applicable export controls and for any violation of such controls, including any United States export and re-export restrictions that may apply to goods, software, technology and services.

4. License and Site Access

Subject to your compliance with these Site Terms, Costco grants you a limited, nonexclusive, nontransferable, non-sublicensable, revocable license to make only personal use of the Services and to install and use the Apps on a mobile or personal device that you own or control. Such grant does not include any right to: (a) resell or commercially use the Services or any Site Materials (defined below), except as specifically authorized in writing by Costco, or (b) use the Services or any Site Materials in any way that is prohibited by these Site Terms (including Section 9). Costco reserves the right to revoke such license either generally or in specific cases, at any time and without notice. Other than the express license stated above, you are not conveyed any right or license by implication, estoppel, or otherwise in or under a patent, trademark, copyright, or proprietary right of Costco or any third party. You may not use any meta tags or any other “hidden text” utilizing Costco's name, trademark, or product name without our express written consent. You may electronically copy and print to hard copy portions of the Site Materials solely for your non-commercial, personal use. “Site Materials” means all materials on the Services, including trademarks, design, product description, HTML text, graphics, other files, photographs, codes, software, software layout, design forms and the selection and arrangement thereof.

Any use of the Services or the Site Materials (including any commercial use, reproduction for purposes other than described above, modification, distribution, republication, display, or performance) not authorized specifically in these Site Terms, without the prior written permission of Costco, is strictly prohibited. We may terminate this license and your right to use the Services if you make or permit any unauthorized use of the Services. Such actions by you may violate applicable law. We reserve the right to have all violators prosecuted to the fullest extent of the law.

11. Financial Material Disclosure

Forward-Looking Statements

The Services, and any documents issued by us and available through the Services, may contain statements which constitute forward-looking statements within the meaning of the U.S. Private Securities Litigation Reform Act of 1995. Forward-looking statements include all passages containing verbs such as "aims," "anticipates," "believes," "expects," "intends," "plans," "predicts," "projects," or "targets" or nouns corresponding to such verbs. Forward-looking statements also include statements or other passages primarily relevant to expected future events or that can only be evaluated by events that will occur in the future. These forward-looking statements are based on the opinions and estimates of management at the time the statements are made and are subject to certain risks and uncertainties that could cause the actual results to be materially different from those anticipated in or implied by the forward-looking statements. Information about factors that could potentially affect our results is contained in the reports we file with the Securities and Exchange Commission, including but not limited to any risk factors we identify in our Annual Report on Form 10-K, Quarterly Reports on Form 10-Q or current Reports on Form 8K. Forward-looking or other statements speak only as to the date they were released. Costco undertakes no obligation to update forward-looking or other statements to reflect events or circumstances that occur after the date the statements were made. In addition, please note that information contained in the Services shall not be included as part of, or incorporated by reference into (nor shall it be deemed to be a part of or incorporated by reference into), any prospectus or offering memorandum of Costco used in connection with the offering or sale of securities.

21. Contact Us

If at any time you need assistance or are experiencing difficulties using the Services, please contact Customer Service via phone or chat; or write us at: Customer Service, PO Box 34622, Seattle, WA 98124.

22. Additional Terms Applicable to Mobile Devices

Part 2 Terms of Sale

By browsing or purchasing a Product through the Services, you agree to the terms set forth in this Part 2 (the “Terms of Sale”). These Terms of Sale are part of the Site Terms, and the entire Site Terms apply to any transactions you enter into through the Services.

23. Eligibility and Restrictions

To complete a purchase on the Services, you must have a valid shipping address within a country that can be selected as part of the checkout process on the Services (the “Territory”). We make no promise that Products available on the Services are appropriate or available for use in locations outside the Territory.

The Products may not be authorized for resale. We may place a limit on the quantities that may be purchased per order, per account, per payment card, per person, per membership, or per household. We reserve the right, without prior notice, to refuse service to any customer or reject any order at any time and refund any money you have paid for such order.

24. Product Listings

25. Payment Terms

Prices

Unless otherwise specified in the Listing, prices shown on the Services exclude all taxes, charges for shipping and handling, and non-member surcharge, if applicable. Taxes and shipping and handling costs (and non-member surcharge, if applicable) will be added to the amount of your purchase and itemized on the checkout page. You will have an opportunity to review these costs before you confirm your purchase. All prices on the Services are subject to change at any time without notice.

Payment

Mobile Payments

26. Order Confirmation; Acceptance.

You will have the opportunity to review and confirm your order, including delivery address, payment method, and other details of your order. You may not be permitted to change your order once it has been placed. We will display or send a notice when we ultimately accept your order, and our acceptance will be complete at the time we display or send the formal acceptance notice. We may not accept or ship your order until we receive payment.

27. Shipping & Handling; No Export by You

You agree to pay all charges that may be incurred by you or on your behalf throughout the Sites at the price(s) in effect when such charges are incurred, including (without limitation) all shipping, handling, delivery, and other charges or fees. In addition, you remain responsible for any taxes that may be applicable to you. These charges and fees will be quoted at checkout. Products and/or Services will be shipped/provided according to the directions you provided during checkout.

Some Products and Services have restricted delivery/availability. The checkout page will confirm whether any Product cannot be shipped to your area, but you must confirm whether a Service is available in your area before placing an order. We reserve the right to change delivery and Services availability and restrictions from time to time and without prior notice.

When you ask us to ship to a Costco location for pick-up, shipping may be without additional charge. However, some exclusions may apply, we reserve the right to add shipping, delivery, handling, and/or other charges or fees, which will be quoted during checkout. Any shipping, delivery, handling and/or charges and fees may or may not reflect actual costs. Some Products may be available at Costco locations. Prices may vary.

In some cases, the delivery method is pre-determined based on the item. To determine if specific delivery methods are predetermined for a particular item, check the Shipping and Returns section of the product page. Delivery methods will also be displayed on the checkout page. We reserve the right to increase, decrease, add or eliminate applicable delivery methods, and/or applicable charges or fees from time to time and without prior notice.

If your order requires shipping or delivery (including orders shipped to a Costco location for pick-up), the order is a shipment contract, and as a result, risk of loss and title for Products pass to you upon delivery of the Products to the carrier. For pick-up orders fulfilled directly from existing warehouse inventory, risk of loss and title pass to you when you pick up the Products.

Any shipping times shown on the Services are estimates only – actual delivery dates may vary.

You agree that you will not obtain or direct shipment of Product for export.

28. Digital Products

Certain Products may be digital applications or digital codes for accessing third-party services (“Digital Products”). When you purchase a Digital Product, Costco may provide you with the opportunity to download the Digital Product via a third-party delivery platform or may provide you with other instructions for how to access the Digital Product. While Costco may, as a convenience, make Digital Products available for re-download, Costco does not guarantee that you will always be able to re-download or re-access previously purchased Digital Products. It is your responsibility to back up Digital Products you have purchased.

Digital Products are licensed, and not sold, to you. The third party that provides a Digital Product to us for distribution is the "Publisher" of the Digital Product. Your use of a Digital Product will be governed by the terms and conditions of an end-user license agreement between you and the Publisher or other licensor of the Digital Products. Access to Digital Products may be for a limited period, as indicated on the applicable Listing, and you may need to enroll in a recurring subscription with the Publisher for access beyond that period. To use or access a Digital Product, you may also need to have or create an account with the applicable Publisher or other third party. Any information you provide to the Publisher or other third party will be subject to the Publisher's or third party's privacy policy or similar terms.

29. Changes, Misprints, Errors, Delays and Cancellations

Subject to applicable law, we: (a) reserve the right to change the goods and services advertised or offered for sale through the Services, the prices or specifications of such goods and services, and any promotional offers and any other Site Materials at any time and from time to time without any notice or liability to you or any other person; (b) cannot guarantee that goods or services advertised or offered for sale on the Services will be available when ordered or thereafter; (c) reserve the right to limit quantities sold or made available for sale; (d) do not warrant that Listings (including product descriptions or photographs) are accurate, complete, reliable, current or error-free; and (e) reserve the right to delay, cancel, terminate or not process orders (including accepted orders). If we do not process an order, we will advise you that the order has been cancelled and will either not charge you or will apply credit to the payment type used in the order. Some jurisdictions may not allow the exclusions and disclaimers of certain implied warranties, so some of the provisions of this section may not apply to you.

30. Returns and Exchanges of Products

Costco has a 100% Satisfaction Guarantee on every Product we sell, and will refund your purchase price subject to the limits stated in the Returns Policy.
