Yes, please include this information (max. 60 characters) in the ‘Additional Information’ section of our checkout. You can get to this gift message section by checking the boxes to ‘add a message’.
If you are ordering for delivery to an address other than the billing address (as is often the case with gifts), then the invoice will not be sent with the order.
So if it is a gift the recipient will not see how much was spent on the order.
