I am referring to actual flavor companies. Those that do not make ejuice, but only sell flavorings.
The market for diy is very small, and I will be the first to say I appreciate that there are some companies that only try to help us “diyer’s” out.
For those that sell ejuice, the concentrates they are selling can be a combo of multiple flavor manufactures, so I bet you will be receiving a mixed response, but it will be even smaller. Most that discover companies like tfa/cap/fa/ etc… rarely go to companies that sell ejuice. Diy tastes better, and you can style it to your own particular tastes.
