How Costco Works
Costco Canada refunds most purchases with no stated time limit, but electronics such as TVs, computers and phones have a 90-day window. Here is every exception, from tires to gold.
If a Costco price drops within 30 days of your purchase, Costco refunds the difference. How it works in the warehouse and on Costco.ca, what is excluded, and how to claim.
Tires
