Just for grinns I have gone and found a bunch of things in big bulk quantities.
Lets say you have the extra money laying around.... and you are lazy or do not know how to work w/ pure nicotine so you buy 100mg base, and you like to vape Max VG @ 6mg and you like to vape nothing but FA flavors.
Let go with easy numbers and quantities you can purchase.....
1 Drum of USP Kosher VG (55 Gallons) $420 (that's 208,198ml) if you pick up from one of the companies 75+ warehouses scattered all over the country.
You will need 14,850ml (just a tad under 4 gallons or 14.85l rounded) of nicotine VG base.... you can get 15l's for $750
Flavors you will need 24750ml (same as 6.54 gallons, 24.75liters, or 50 500ml bottles rounded up) (@ an average of 10% flavor usage), you can get 50 500ml bottles of FA flavor for 32.99 each before shipping for a total of $2649.50.
Now lets say just for argumentative sake you choose to use a new 30ml amber glass bottle with a crc dropper for each and every bottle you make, and you do your mixing by weight so you do not need a bunch of other mixing supplies except a glass funnel and a little upper body strength to control the main bottles to put into smaller bottles for easier handling (we will add an extra 50 for the flavors, and then 1 extra for nic, and 1 extra for vg) you will need a total of 8,302 30ml bottles and droppers this can be had for $2822.68 before shipping if purchased all at the same time ($.34 each INCLUDING THE D**** DROPPER in otherwords THE DROPPER IS NOT SOLD SEPARATELY OR AN ADD ON ITEM!!!!)
So for our totals we come up with a GRAND TOTAL OF $6,650 rounded up and before shipping of materials. For 8,250 30ml bottles of juice!
That is just $1.24 per completed bottle of juice (or $0.04 per ml), and say you vape 30ml in 2 days that would last you 45 years or so. Now say you smoke 1 pack of cigs a day, pay $5 a pack (thats what they are where I live right now roughly for the Big names) that is $82,125 to smoke for 45 years (assuming taxes don't go up, and prices on cigs themselves don't go up.
Now I completely lost my train of thought on whey I was writing this post between doing the quick research with my mad GOOGLE FOO skills however there was a point to it and if I can remember I will let you know lol.
OH I might add that I found these prices from vendors plastered all over these boards with the exception of the glass bottles
