Submit by Mail
When rebate items are purchased at a Canadian Costco Warehouse, a separate Rebate Submission Form is automatically printed at the cash register itemizing any eligible products. To submit a rebate request via mail, just complete the form by entering your name, address, phone number and e-mail address (optional) and mail it to the following address:
PO Box 10668
Thunder Bay, ON P7B 6V1
If you purchased an eligible item on-line, you may open and print the required form (in .PDF format) from the link provided on the item page or by selecting the "view mail-in form" link below. Please complete the form and mail it to the address listed on the document.
Save time. Save a stamp. If you are a Costco member, and reside in Canada, you can now submit your rebate requests on-line for warehouse or costco.ca purchases. Submissions must be entered within 30 days of expiration. Simply select the "submit" button below to begin the process. To submit a rebate through our website, the 'pop-up blocker' on your computer will need to be disabled or hold the CTRL key while clicking on the OK. By holding the CTRL key, this will communicate the pop-up is allowed.
