  • General merchandise: Most items can be returned at any time for a full refund under Costco’s 100% satisfaction guarantee.

  • Electronics & appliances: Must be returned within 90 days of purchase/delivery (TVs, computers, cameras, appliances, etc.) for change of mind.

How to return an item to
Costco

  • In-warehouse returns: Take the item to the returns desk at any warehouse. Bring your membership card, receipt optional (purchases can be looked up by membership). Refunds are usually processed on the spot.

     – Log in at costco.com.au → “My Orders” → request a return.
    – Print the prepaid return label or request one by email.
    – Pack securely with all parts and drop at the post office/courier.
