Actually, I was just in a new B&M last week, opened mid-June. Spent maybe a half hour talking with the owner. He's into it about $40,000.
Like many, my entry to vaping was as a B&M, for all the reasons Bad and Eddard cite. That was with a 650 ego and CE5 kit. Helpful staff, lots of hands on "training", and got me hooked. (Dang, whatever happened to "first one's free?

) Actually got my MVP there as they had it for only about 20% more than online (before Fasttech had them), and just picked up an Itazte VV at another B&M last week. Again, within about 20% of online, and worth the extra to support local. (And that shop also gives me a senior discount - haven't seen that online!)
And I do try to get at least some juice from several of my nearby B&Ms, to do a small part. I like having them around, and want to encourage them.
But things that are 200% of online, well, I may be crazy, but I'm not stupid
And very true, too, that buying online can be like the "pig in a poke" situation, not knowing really what it feels like in the hand, and so on. It can be a substantial investment for something totally new and unknown. I don't know many (any?) who want to dump significant $$ into something without having a clue that yes, indeed, this is better than what they're already doing. Heck, when I started, I got help on juice flavors from the store staff, discussing what I'd been smoking, tasting at the juice bar and so on. Can't do that online either.
