We currently do not offer a special setup for gifting books like a gift message or a gift box/bag.
However, you can safely send the book to your gift recipient by just typing in their address in the Shipping address instead of yours (make sure you use your Billing address). The packaging does not contain a receipt, so they won't know how much it costed or from who it came from.
Also, if you use your email address, phone number and name during the checkout process, you will receive tracking information on when the recipient will receive the package.
