Matt & Company will help you with everything you could possibly need to get started. They're a great bunch of guys, despite their musical tastes (REALLY hard metal band stuff) and they're very knowledgeable.
I keep going back to try different flavors and when I was in there yesterday, a couple senior ladies were getting started, too...
It doesn't cost a lot to start (I got out of there with the whole set up for the cost of a carton of cigarettes) and I just completed my first week of no cigarettes in 35 years!
