Be careful, two things I've noticed at the B&M stores.. First is that most of the owners are vapers themselves.. and that means they are using their best stock and favorite mods.. and many of them have a smug attitude towards anything less, like the ego twists for instance. I don't think it's intentional, and I truly believe they want to help you- it's just that their predispositions tend to interfere with guiding you towards what is best for you. This is just my experience- your mileage may vary.
Second.. most only carry a handful of items and brands.. you will find very limited choices at these stores. You will also find a lot of cheap chinese knockoffs.. Just TRY finding an actual JoyTech Ego twist at one of them..
Good luck
My town, Waco, TX, has a mess of head shops and smoke shops that carry only knock-offs and cigalikes, which I've found to be a waste of time, money, and sanity. The owners and workers, usually foreign, don't vape themselves and are just trying to sell whatever inventory they got.
I finally found the only dedicated vape shop in the area, and it's made a huge difference. I've become friends with the general manager and some of the other workers, all of which are ol' vapin' pros. They do charge full retail on about everything except their juices, but I understand, it's a small market and they gotta keep the lights on and employees paid.
