When I was under 18 and liked to enjoy smoking cigarettes, I decided to chance it and order a vaping kit online - since I didn't have many reliable people to supply me locally with conventional tobacco (which is gross anyway..).
Got a ring at the door, signed it and that was it... No ID required, unlike the strict shopkeepers.
Although this was about 3 years ago when the laws about vaping were sketchy. But I would 'risk' it.
What's the worst that could happen? The desperate delivery guy who has a lorry load of deliveries to do says 'NO' and you get a refund from amazon?
Life's too short!!
