Here is the Costco Canada coupon policy:
Costco Wholesale does not accept general manufacturer coupons.
We have our own coupons and promotional offers, which are distributed to members in the mail and at our locations at various times throughout the year.
We are able to offer consistently low prices because our buyers negotiate the best deals with our vendors.
Manufacturers often will simply ‘load’ the cost of a coupon program into the original pricing of their product. We will not permit our vendors or buyers to do this since there is no advantage to the member.
We also do not price match.
