Yeah, I'm actually delighted by the idea that there are enough parameters involved that an e-liquid deserving such high prices could actually evolve, but for me to lay out my dollar I'd need specific information about innovative ingredients or something else really impressive; at this point we already have a good number of sellers who can do terrific, complex things with the standard flavorings at a decent price (and still make a handy profit). And some also-affordable real innovations.
"Tastes really delicious" doesn't help much, since that's frequently and enthusiastically said about a lot of lines, from the extremely basic DIY-type to the familiar Chinese bulk juices to very skilled and interesting recipe developments.
I honestly do appreciate artistic packaging - all other things, including price, being equal, that'd be a factor for me.
Looking forward to reading the interview, and thanks for that!
