All Instruments are shipped signature required. We primarily use UPS for our instrument shipping method but may use FedEx depending on location. If you are concerned about signature UPS typically will have your package held by a CVS or UPS Store if they miss you at home!
Please note that if the billing address does not match the card being used it will decline and may put a temporary authorization each time you hit submit. It WILL fall off when the system batches out. If you do not get an email receipt with your order confirmation number, it did not go through.
