I am very new to vaping and people are freaking me out about posting to stock up on supplies. Due to the passing in NY, which is a load of crap, it seems they think it will spread to other states and it probably will. How long does the cartomizers keep if unused? Also I have just refilled my first cartomizer with e juice from another site besides V4L and it made me sick. I posted about it and it seems to be the thought that maybe it is the brand or could be that 35% VG is too much. I intend to use the prefilled cartomizers until I can get a juice that is right for me. Also I read that the juice stays good for 6 months. There is another thing I saw, some mods (I don't know what mods are) use regular batteries from the stores. What does everyone make of all of this and should I really be stocking up? Any opinions and answers to my questions are so appreciated!
