I'm getting ready to stock up. The Vapocalypse Calculator informs me that four liters of 100mg/nl liquid nicotine should last me at least twenty years. It's an investment, so I want to be sure I get good stuff. I'm going for 100% VG because @Rossum's wonderful thread on nic storage leads me to believe this will store best. I want something smooth with little throat hit. What vendor should I use? Bonus question: Is there any reason to choose amber over blue glass bottles (I'm planning to transfer the nic into 100ml glass battles for freezing)? If there isn't, I'll opt for blue, because it's prettier, but if amber is better, I'll go for utility over beauty.
