Welcome, and congrats on kicking the smoking habit!
Answering your other thread question on saving money...
Most of us end up buying tanks that you build your own coils for. So no more spending on stock coils!
You can save money by having a look at some of the cheaper (but still excellent) online juice vendors like Drip Drop and Rejuiced
And with a little time and energy, you can save a lot more money by making your own eliquid.
It all depends how much time and energy you want to invest, vaping CAN be a very cheap hobby, if you don't succumb to the urge to buy ALL the things (most of us here have had it/still have it, and we will lure you down that dark but glittery path if you allow us!)
