I don't wish to bash anyone---vendor or poster---for expressing frustration. In general, however, I think this problem is a sign of the coming times, and we should all prepare for a lot more of the same.
Gene at NLV worked out the recipe for Bounty Hunter, but he doesn't actually make the juice. He gets it---premixed and already bottled and labeled---from his juice supplier (a larger operation), which is encountering difficulty in obtaining the flavoring ingredients from its suppliers. So, what we have is "discontinuities" in the supply chain, meaning disruptions, delays, and even dead ends.
Modern mega-capitalism is built on incredibly complex systems. Think of an auto parts store. Right now, you can obtain just about any part for any car made in the last 50 years within a single day (sometimes within hours) because of the coordination between massive but largely invisible sub-layers of the commercial economy: parts suppliers---warehouses, used salvage inventory, etc.---and delivery options---ups, fedex, usps, etc. As the global economy collapses, however (which is already underway and accelerating) the problem of breakdowns in all supply chains will become increasingly obvious.
We have grown accustomed, habituated, and even addicted to the consumer dream of "having anything we want, and having it NOW." Whether it's blueberries from Peru in February or eliquid-on-demand, we have become spoiled with convenience and immediate gratification. That fantasy is going belly up within this decade. The Titanic has already hit the iceberg, and though the passengers are continually reassured by the crew (meaning the Powers That Be and their propaganda organ, the mainstream media) that all is well, the ship is going down very soon, and nothing can save it.
Sorry, I know this is an ecig forum, but this post truly isn't off topic, given that we're already experiencing the strain of "systems overload" in the juice marketplace. Goldrush and Saddle Up! are already gone forever because NLV's supplier/manufacturer can no longer obtain the needed flavorings, Bounty Hunter is available only sporadically, and there's nothing Gene can do about it.
I'm sure Gene would love to keep his customers happy by selling all those juices in unlimited quantities, but his hands are tied. He has no magic wand.
