A lot of people will argue that the quality of the
juice here is much better. I'm not sure about that. I like both Chinese
juice and North American
juice, though admittedly I like North American juice better. Everything in China is cheaper though, a pair of $200 Nike sneakers like like $10 or something apparently. Everything is made in China, including the majoirty of e-cig products, so there's another reason.
As for Customs, there are a lot of threads about this but my opinion is that the risk of packages getting stopped is much lower than most people think. I've had dozens and dozens and dozens of juice from the US for example, even some declared as "nicotine juice" that got through no problem without issue. I had had one issue in all of my shipments and it wasn't even juice, it was a kit (no biggy because I won it and they reshipped). With the sheer amount of packages that pass through the Border each day, there is no way they can care about or look at every single package, probably not even half of them. Plus, some of the Border Agents are probably vapers and realize how dumb the advisory is.
