I NEEDED to save some money on juice since i was flying through it ever since getting my sigelei. What i did to save money is purchase some VG nic base from ecigexpress, and some VG USP from Amazon. I dont actually vape flavored juices normally, and I use drippers almost exlusively. I was able to get enough materials to basically make just over 2 liters of 6mg nicotine juice. I can now poduce my juice for approximately 95 cents a bottle. It isnt hard to do at all with all the calculators available to you online.
My base is 60mg, so to make a 50ml bottle of 6mg, I basically put 45ml of vg in the bottle, then added 5ml of my base and shook it vigorously. done. about ive total minutes of work (because i had to open the new bottles and boxes, etc.) and I have a fresh 50ml bottle of sauce.
If you use a tank system and need a thinner juice, you can order your base in 50/50 PG/VG and then buy one liter of each for mixing. It definately isnt as daunting as it seems. and if you are really wanting flavors, just order some flavors and start simple with single flavors. hell, if you mix up two single flavors you can always just mix them together in a small bottle to see how they taste combined too.
seriously, if you want to save money on vape sauce, DIY is the way to go. With the money I am saving now, i can treat myself to some of those high end juices every once in a while and not feel bad about the extra expense, or be upset if it turns out the hype is more than the taste.
