Costco Canada Return Policy: Warehouse, Online Orders and Electronics

Quick answer: Costco Canada offers a merchandise satisfaction guarantee, subject to specific exclusions. Electronics and major appliances listed in its policy are generally subject to a 90-day return window measured from purchase. A warehouse purchase and a Costco.ca order have different practical return routes; start by checking the official Costco Canada policy for the particular product.

Warehouse purchases: receipts, packaging and the return counter

For a purchase made inside a Costco warehouse, bring the item to a Costco warehouse. Costco says original packaging is preferable but not a requirement for a warehouse return. It prefers the original receipt and says it will do its best to process the return even without one. This is different from assuming that every non-member or every untraceable purchase can be refunded.

If you received an item as a gift without being a member, check the non-member gift-return guidance: Costco states that a non-member needs the original receipt, otherwise the purchasing member must handle the refund. Keep the member purchase details ready if you need the warehouse to locate the transaction.

A Costco.ca order offers two main routes

Costco describes two ways to return an eligible online purchase: take it to a warehouse with your order confirmation, or sign in to Costco.ca, open Orders & Returns and select Return or Replace Items beside the relevant order. The online-order return instructions describe both methods and the available reasons for a return or replacement request.

When Costco arranges a standard return label, its help page says the label can arrive by email within two to three business days. For large-item pickups, the carrier may contact you within one to two weeks to arrange a date. A pickup-and-refund request may take three to four weeks to complete. Those are Costco’s stated process estimates, not a promise that every refund will appear in that time.

The 90-day category limit is not a universal rule

The warehouse guarantee has particular exceptions. Costco names televisions, major appliances, computers, tablets, cameras, mobile phones and other designated electronic products among items with a 90-day period; mobile-phone returns may also depend on the carrier arrangement. Do not assume the ordinary satisfaction guarantee overrides the category-specific terms.

Other exclusions and special verification steps apply to particular merchandise such as bullion, certain diamonds, gift cards and tickets. Before buying or returning an unusual product, consult its receipt, listing and the Canadian membership conditions rather than relying on a broad summary of the satisfaction guarantee.

Practical examples: lost paper receipt and a delivered appliance

You paid at a warehouse but cannot find the receipt. Costco says it will try to process warehouse returns without the paper receipt. Bring the item and your membership information and let the warehouse check the actual purchase. A gift received by a non-member is treated differently, so the original receipt or purchasing member may still be necessary.

Your Costco.ca appliance was delivered to the curb. Do not assume an online return means mailing a large appliance using a normal parcel label. The official instructions state that pickup arrangements depend on delivery type, and that an item that arrived boxed should be packaged for pickup. Start the request in Orders & Returns and follow the carrier instructions.

How to reach the right Costco team

The Costco Canada customer service page lists online self-service, phone contact and local-warehouse options. Use Costco.ca support for an online order and the warehouse return counter for a purchase made in person. Have the order number or membership information available; do not send payment-card details through third-party sites.
