In over 9 years of vaping, I have never bought from a b&m. I went into one or two in the early days and was not impressed with the young know-it-alls working there or their selection/prices. I don't feel bad about it, either. I have had friends who won't shop online so they go to the local stores. I figure it evens out and many of the shops sell online as well so they have the best of both worlds.
The guys at the shops I liked were young, but they were good to me. Answered my questions and helped me out as a newbie and never were condescending.
And I know a lot of us crusty old farts who will not shop online for any thing, for any reason. So the B&Ms were nice to have around.
But yeah, their selection would not do it for me now.
