Honestly it's pretty easy. Update on my juice I made it turned out awesome except I needed to add more cherry. Subtract the cherry and you got an awesome creme soda and I don't normally like creme soda.
I don't know if I'm allowed to do this but I got my stuff at ecigexpress.com. Here's the deal I spent $60 for 4 bottles, 7 flavors, nicotine, pg, vg, and syringes, I have enough stuff to make 30 bottles at 10ml each which is equivalent to $300.00 dollars. And I will still have plenty of nicotine and flavoring for many more and expect next time to spend about $10.00.
If you vape a complex juice then yes keep buying it but if it's simple like a tobacco or one or two flavors you should try making your own juice. It's really easy but you should stir everything once it's mixed instead of shaking it vigorously. I didn't get one of my juices mixed just right and took what I think is a straight shot of nicotine. Made me a little woozy but I learned from my mistake. If you think later you might make your own, do yourself a favor and save all of your empty glass bottles and throw away the plastic. Plastic can hold residual flavors.
Hope you find a good Cherry Soda and keep vapin on!
