To a certain extent, what you've said is true, Flt Simulation. But as of August 8, 2016, the Deeming Regulation turns all vaping hardware into "tobacco products." Many states have laws prohibiting purchases of tobacco products via the internet. Also, many states have laws about B&M retailing tobacco products without special licenses (i.e., expensive), store locations, and such. And no one knows just when or how BATF (Bureau of Alcohol, Tobacco and Firearms) will start seizing domestic or international shipments, or what Chinese manufacturers' reactions will be to having stuff snatched by the BATF.
You can choose to take your chances. Obviously, you have. Many of the rest of us have chosen to be prudent and stock up for many years (or a lifetime) of vaping supplies.
