We do not request a signature. Gifts over $500 automatically require a signature per UPS requirements. There may be situations where the UPS driver may require a signature even though we did not request it. Unfortunately, we have no control over that. UPS leaves those decisions up to the driver. At the driver's discretion a package may not be left. In this case a call tag will be left with instructions on how to retrieve their package. Packages usually go to a local UPS access center where the recipient can pick it up. If it is not retrieved by the recipient after a certain period of time the package will be returned to us. Unfortunately, that is something we cannot control.
