All orders shipped by PB Tech are sent via a courier with a signature required for each delivery. In some cases, and only where you have given the courier company permission to leave orders at a designated location, your order may be delivered without requiring a signature. All orders sent by PB Tech are fully insured in the unlikely event that your item(s) are damaged or go missing in transit.
