In the UK they come in a Bubblé wrap envelope, no one can tell or cares what it is and in the midst of lockdown there's so many deliveries . Sometimes they put a return address sticker, ask them not to and it will be more than stealth.
i paid for the dvd package lol and got my order inside a copy of "Daddys Home" with Mark Walhberg and Will ferrell. lol. inside a bog standard padded envelope, no return addresses on it.
Don't worry mate, the packaging is always discreet even without the stealth packaging. But you can always use the DVD option (as mentioned above) and get a decent piece of cinematography on top
