Might try www.wizzardlabs.us they specialize in DIY and you can get 100mg nicotine solution 500 ml for only 56.99, pg, vg, bottles, anything you need to make your own juices and cheap. They use usp grade kosher 99.7 % pure unlike so many for cheap! the pg and vg like the nicotine come in all sizes for example 250 ml 5.49 vg. This is how I find the rip off companys I have seen 30 mil vg go for 9.00 this is crazy and I don't do business with these companys. Also stay clear of Chinese juice makers they use all kinds of chemicals that are suppose to add shelf life to them but make most of them taste impure and just nasty.
