Watch Out For

  • Anything you submit to Costco's site — reviews, photos, ideas — becomes Costco's to use royalty-free, forever. Costco's Terms grant a perpetual, irrevocable, royalty-free, worldwide license to use, copy, modify, adapt, publish, and sublicense any content or ideas you submit through the site. The license has no expiration and no compensation. This applies to product reviews, photo uploads, and any written submissions.
  • Costco can terminate your membership at its discretion and without cause. The Member Privileges and Conditions state that membership 'may be terminated at Costco's discretion and without cause.' However, the 100% satisfaction guarantee on membership means Costco will refund your membership fee if you cancel for any reason.
