I also prefer my own diy juice. If you get a hankering for a certain flavor, you can just whip it up and vape it, at least with fruit flavors, which don't require much steeping. I love diy, it's a shame so many folks are intimidated by it. I was lucky that I didn't have a big stash of premade juice when I started diy. Most of my juice investment was with flavors, pg, vg, and nic instead.
If I don't, does that still make it the best value!
