Just a question for everyone.. I get all my nic at NN, I really trust them and like their quality. Everyone seems okay with cheap nic from places like heartland, but isn't it too cheap? How comfortable are you all with the quality of the product?
I think it just depends on what you like, and what you're used to. What one person finds disgusting and awful, may be totally fine for another person who can't tell what the first person is talking about.
I personally like Chemnovatic nic and Carolina Extracts SuperCritical Nic. I have about 16 liters of the former, and another 5 or 6 of the latter, all broken down and frozen. I paid $100 per liter (give or take) for the Chemnovatic, and the SuperCritical has always been $150 per liter. Neither company has ever offered sales to the best of my knowledge.
I also have some NN which I just purchased because it was pre-packaged for freezing, but I've never even tried it, and not really counting it as part of nic stash despite having 3 liters of it. NN is also not cheap (as compared to other nic available on the US market). You can also purchase pure nic which is 10x the concentration of 100mg/ml, but I do not believe this forum allows posting of that -- whatever the case, google is your friend (although nic from China may not be).
I'm happy with what I have, it works for me, I have enough to share with family and friends, or over a century's worth of nic for myself

Whatever you do, stock up on
something!
Cheers.
