Good morning Linda, and welcome to the forum.
I'm a new guy too so I can relate, I know I want to do this but where do I start?
Well, the guys are right, you're eventually going to want a good piece of equipment which gives you control over your vaping experience and eliquid that offers a wide range of taste. In fact they've almost got me convinced, that Innokin iTaste looks like a good piece of gear and at a very good price.
I currently use rechargeable ecigs with cartomizers and a thing called an eGo which is a big battery with a tank of ejuice sitting on top. The eGo is the very primitive baby brother of the Innokin they were talking about.
Question - Are you using disposable ecigs? If so your greatest economy will come from switching from disposables to reusables. Cartomizers and ejuice cost a lot less than replacing disposable ecigs every day. Also using eliquid will open up a world of flavor choices you can't imagine => RY4!
Like I said I'm looking at that Innokin myself but you should know they are big. If you feel more comfortable with something smaller and more cig-like you still have choices both economical and tastee.
Welcome aboard, keep vapin' - Red
