Our Double Guarantee

It’s always fun to try new things. But what happens when you don’t like them? Costco takes the risk out of shopping by offering members a Double Guarantee.

If you aren’t satisfied with the products you buy at Costco, you can return them for a full refund, with limited exceptions as noted below. Additionally, if a Costco membership isn’t what you thought it would be we will refund your membership fee in full.

These are just two ways that a Costco membership is different and tries to make sure that you are nothing less than 100% satisfied with your total Costco experience.

Product and Membership Guarantee

On Membership: We will refund your membership fee in full at any time if you are dissatisfied.

On Merchandise: We guarantee your satisfaction on every product we sell, and will refund your purchase price, with the following exceptions:

  • Diamonds: 1.00ct or larger: Members returning a diamond over 1.00ct must also present all original paperwork (IGI and/or GIA certificates) at which time they will receive a Jewelry Credit Memo. Refunds will be approved upon positive verification. This process may require 2-5 business days.
  • Watches: Refunds on all watches will be approved upon positive verification. This process may require 2-5 business days.
  • Special Order Kiosk and Custom Installed Programs: Custom product(s) manufactured to our member’s personal and unique specifications cannot be returned or refunded, except for warranty repair/replacement due to failure to meet specifications.
  • Costco may in future restrict its return policy regarding other products. Restrictions will be shown at time of purchase.

Nothing in this Guarantee, or any other restrictions at the time of purchase, limits any rights or remedies that you may have under the Consumer Guarantees Act 1993.
