So far, I've done pretty well.
I've gotten two juices I wanted NOTHING to do with, but they were free samples, and I passed them on to family member who vapes.
I bought ONE 15ml bottle of a flavor I didn't like, and that was a whopping $5.50. This also got passed onto the same family member.
I have two bottles of juice that I liked, but after sitting for a couple of weeks, the flavor got too strong for me. My fiance took those off my hands.
Lastly, we have a handful of tiny bottles from Halo neither of us liked - they were part of the sample packs we bought with our initial kits. Those, sadly, are still sitting around.
At this point, I've wasted more money on hardware that didn't work well than I have on unvapeable juice.
