TL, you know if your in a bind over something you can email the companies and just ask.
I'm sure you will find someone who will meet your special request. Demanding that all companies provide such all the time. Doesnt seem necessary to me.
Unlike Milk that goes bad after a week and needs to be in a fridge, and is large and bulky....e-liquid lasts at least a year or two at least, needs a cool dry place(like a cabinet in a room AC) is small and a lot of "stock" doesnt take much space.
Unlike Gas, where any normal person can Only carry as much as there vehicle can...it's easy to have plenty of e-liquid.
Unlike Cigs, where you have a whole two flavors to choose from and most folks pick one flav one brand and stick with it for years........e-liquid has 100's if not thousands of different flavors. And just about everyone I know has a few GoTo flavs, but has many other try it out, just b/c it's fun bottles around.
And Unlike Cigs, For the same price as an average carton 65 (that would last me a whole week).......I can get 4 30ml bottles with shipping(of good stuff no cheap junk).....easily a 40 day supply.
So its easy to stock up...to completely run out just seems unlikely to most of us. Now a fav flav...sure but All of it?
So not that I am disagreeing with you as I have a 2 yr stockpile, will save thousands on what I would have spent on cigs but not everyone has the cash to stock up.
