I haven't yet, because it feels a bit like accepting defeat at this point. My one true love of vapes since the very beginning of buying juice online has been Beeblebrox by The Vapor Chef. I love that juice to pieces, and am so dangerously close to just throwing an order at him to get more of it - but I've got a lot invested in the DIY side of the hobby. To go back to vendor juices, like I said, would feel like I gave up in a way.
I've gotten a good few recipes in rotation at the moment, a lot of experimental stuff, a few bottles of stuff I've found here and elsewhere - so I'm a happy vaper, no doubt about it, there's tastiness stashed in drawers and on shelves all over. But I'll never forget Beeblebrox. Never.
What's worse, I can't even begin to come close to what I remember it tasting like. (Hell, I don't even know where to start properly.) Either way, no, no more vendor juice - not since that first DIY vape mail box came in.
