Do most premium juice vendors use the same flavorings that are available for sale on most DIY e-juice sites? Besides the vendors that use their own extracts, everything else is pretty much the EXACT same stuff we can buy and mix? I ask this because I understand a lot of people are willing to pay for well made juice with lots of exotic or subtle components that make it appealing. But for the most part, if you knew their recipe and had the same flavorings that you can buy, then you can make the exact same juice? I have a bunch of DIY stuff that I recently bought but haven't dove too deep into and my boyfriend told me I should make my own juices and sell them. I told him I was just doing this for fun and have no idea what I'm doing, nor do I have any good recipes that I've personally made. And he's like "What, just mix some crap together, record your results, and see if it tastes good. That's what the other vendors do probably." I mean, besides the cute personalized notes, confetti, candies, trinkets, and custom labels, its all about the juice in the end and they don't do anything substantially different?
