I hate to say it but buying a concentrated flavoring that you can just mix with pg vg and nic is about as cheap as it gets you can make 100ml at 10% flavoring for about 9-10$ it really doesn't get much cheaper than that I mean you could try and diy a similar mix but then you would be buying a bunch of flavorings and it probably won't come out the way you would like it to so I would just stick with what you have
I understand where you're coming from, but this particular concentrate costs almost double than most other concentrates, over $9.50 for 10ml. So, when I make a 120ml bottle, using 20% flavoring, that's almost $25 for the flavoring alone.
I have a ton of flavorings, been DIYing for over 2 years, so I know the savings. I just hate that I can't figure this one out, and make something close. I also don't want to be dependent on one vendor, considering the coming regulations.
Thus my quandry...
