I buy my juice by the liter, I've been doing this for a couple years, I get a liter for $100 so I save a lot of money doing it that way. I keep it in my fridge and one bottle lasts me well over a year, no change in color or flavor. I vape Cinnamon Red Hots (yes I have heard about vaping Cinnamon but I've been vaping it for 8 years and I'm still here and healthy) 24mg. I've ordered a gallon, it's only $50 more and with the FDA doing their thing I think it's practical. I'm splitting it into 4 liter amber glass bottles but even if some goes bad down the road I've still saved money, I also have plenty of 100mg. nic in the freezer just in case, but I really love this juice and I don't think I can make it as well as my e juice vendor.
