When you try them out, and find you're comfortable with a level, order an extra bit of juice that is one level higher in nicotine. (ex: If you like 18, keep a sample of 24 laying around). When you vape, the nicotine isn't absorbed into your body as easily as smoking. So you might have to vape more (plus you'll find it hard to stop vaping, it's so much fun). I suggest the bottle of juice, one level higher for those days where you just need that punch, and you're regular level doesn't quite cut it. Final point, juice is your lifeline, you can never have to much in reserve. Most people say to buy samples, but I personally consider that a luxury that you should strive towards, when you have a stockpile of juice. Since I'm still new, If I have a juice I don't particularly like, I at least know that it's there, and when times get tough, I'll have something to fall back on. It is a tool to keep me from smoking first, and a matter of enjoyment second. I usually will order in bottles of 30ml depending on if it's clearance, or I've just heard alot of good reviews. 30ml will be cheaper, then buying 30 ml, in 5ml increments. This is what works for me personally, but I find I'm not to picky about taste. Another general rule I've heard is at the very least, order juice, when you're just opening you're last 30ml bottle. These are the strategies I've found work for me, the sampler is definitely a good starting point, and is how I started. It'll give you a feel of what you like and don't like, but keep in mind, shipping takes time, and plan accordingly.
