At $10 for a 30ml bottle, I'll buy pretty much anything Gene cooks up. If they turn out to be a miss for me rather than a hit, that's OK. Later, after they're discontinued---as numerous of Gene's former concoctions already are and which will no doubt continue to occur in the future as supply chain problems worsen and further pricing conflicts arise---I'll still have bottles in my stash of what will then be collector's items. LOL.
Personally, I'm not into stockpiling juices out of fear they will vanish, but---especially given Don's announcement that BackwoodsBrew is discontinuing both Ejoker and RY4---I have no doubt that at least a small percentage of veteran vapers will likely begin doing just that with their favorite retail nicquids, and thus become the equivalent of "juice survivalists."
Who knows? We might even see an underground gray market develop for juices that are no longer available. Like bidding wars for a bottle of BWB RY4 or VapeTV Bounty Hunter. LOL.
