There are a few reasons an order can be returned to sender but most often it is due to an undeliverable address. Other instances include the package being unclaimed at customs or refused/returned by a customer. Once we receive the returned product, we'll contact you with what steps to move forward with and usually, the correct address to resend the product to. New shipping charges will be applied for orders that have been unclaimed at customs, returned by customers, or had an incorrect address originally provided.
