Yes, you can cancel your warranty, often for a full or partial refund.
When you cancel your plan within 30 days of plan purchase and have not made an approved claim, you will receive a full refund.
If you cancel your plan after 30 days of warranty purchase and have not made a claim, you will receive a prorated refund based on how many days remain on your warranty term minus a 10% cancellation fee calculated from the prorated amount.
Refunds are not available on any warranty plan with an approved claim.
