We use FedEx because of reliability issues with other carriers but offer flat rate to help with the cost. Signature is required upon delivery due to the value of our products and for our customer’s protection. If you need to override the signature requirement, create an account with FedEx Delivery Manager to specify your delivery method. If you need faster shipping, many of our products are available via Amazon Prime. If you are not located in the US, we have distributors worldwide that may have better shipping options for your location.
