I need reall good repo juices like really juice manufacturers from the core,
Um, "Say what, Willis?"
I would like to offer you advice. Trouble is I'm not understanding exactly what you're looking for by way of advice. Granted I have congenital brain damage, but I'm not sure my cognitive issues are in play here.
For myself, I'm going to try stocking some more unflavored 18 mg strength base ejuice. I want that strength pre-mixed because I have not the space or inclination to try diluting 100 mg strength nicotine myself.
As mentioned I got a few issues which slightly impair logistics, math. Don't want to foul up. So yes, I'll happily pay a little premium to get pre-mixed base. Though I know soon that premium will no longer be just a "little" one.
I can get flavorings, if I even desire them, affordably enough. Flavorings themselves will not be banned as they can be used in food making, or other sundry uses. I don't really purchase juices from vendors any longer. Pardon my vernacular but "DIY, It Werks Fer Me!"
Even if I'm only adding flavors to a pre-done base juice.
