Yes, you do. All orders require a signature on delivery for goods to be released. This is to ensure the safe delivery of your order to yourself.
We recommend getting your order delivered to your workplace if its more likely you will be there to sign for your order during the day.
If you provide special instructions to the delivery provider to leave your order without a signature, we cannot accept any claims for loss or damage to your order.
Please refer to here for further information on what occurs if your not home when your order is due to be delivered.
