We reserve the right to determine the fastest and most cost-effective manner of transportation for all orders that qualify for free shipping. Our shipping carriers cannot deliver to PO box or U.S. military post office box addresses, such as APO and FPO, so we require a physical street address for delivery.

If the item qualifies for free shipping, you will be charged the original shipping cost and are responsible for shipping the product back with the shipping carrier of your choice.

We must receive the item undamaged. We recommend you package it accordingly and purchase insurance for higher-priced items to ensure you receive the full refund minus any incurred fees as applicable. We reserve the right to refuse the return of accessories.
