If there is any deviation from these delivery guidelines, there is no insurance coverage. Your package will be sealed with brown tape around the flap closures. Please closely examine the package upon receipt. If there appears to be any sign of tampering, do not accept the package and contact us immediately. We also offer free USPS Express shipping if your address is not accessible via FedEx delivery. International shipments have a $110 flat rate for shipping and returns. For all orders over $100,000 shipping and returns will be priced based on total value and destination.
