Thank you for your feedback. We did receive your email on 10/15 and promptly responded the same day to let you know that we had contacted FedEx to begin the claims process. Once a package is turned over to USPS or FedEx, delivery and liability are in their hands.

All orders are automatically insured up to $100 unless additional insurance is purchased at checkout. We understand how frustrating shipping delays or losses can be and are working with the carrier to resolve this as quickly as possible.

We truly value your business and will continue to monitor your claim and keep you updated as we receive information from the carrier.
