A fire sale would be a better outcome than I expect. I'd be more afraid of prices on what's going to be banned going up exponentially while it's still allowed to be sold.
juice concerns me more than anything. Much as I've read and researched since starting vaping I haven't felt I've ever found a definitive answer as to how long unopened juice will stay useable, whether or not to refrigerate and etc........maybe it's not really known yet. Lots of differing opinions can be found for sure.
The only thing i have found from my experience somfar for flavoured juice is, the cool dark place seems right, had juice for a few months so far and its still good. So a year doesn't seem like a crazy stretch. I did have a bit of a panic last month cause i had some alice in vapeland go bad at cool dark conditions within 2 months, and i love love love alice but the concensus seems to be that does have to go in the fridge or regular order of small fresh batches.
I have a bunch of nude nicotine in the freezer, the armor stuff.. Hopefully it came good and lasts. Seemed to really defeat the point to open it, check it and then freeze it.. Liklihood of it being off seem pretty low also.
Gets to a point where theres only so much prep that can be done.
