Travel policies can be canceled within 10 days of purchase for a full refund. Cancellations and lowering coverage are not permitted after the 10th day.
The third paragraph on the second page of the policy states,
"All premium is refundable only during the ten (10) day review period from the date of purchase (or from the date of receipt if mailed) provided You have not already departed on Your Trip and You have not incurred any claimable losses during that time. If You depart on Your Trip prior to the expiration of the review period, the review period shall automatically end upon Your departure."
