You want Tasty Vapor's Blueberry Cheesecake at 24mg, right?
You have two options. The second option will cost you less per ounce.
First
Go to
Tasty Vapor
Under "Product Range" pick "
e-liquids 1 oz."
Cheesecake
e-liquid is on the second page.
Select 24mg for the strength.
Pick the % VG you want. (24mg is available with 35% VG or less)
Select the flavors you want added -- just blueberry or do you want a second flavor mixed in?
Order it.
This will cost you $15 + $5 delivery. ($10 + $5 when cheesecake is a flavor of the week.)
Second
Do the same as above but, instead of selecting 24mg, pick 48mg. (48mg can have a maximum of 10% VG)
Next, under "Product Range" pick "2 oz doublers."
Order the blueberry cheesecake the same way you did the e-liquid.
If you want higher than 10% VG in what you vape, take care of that here (see below.)
Order both items.
This will cost you $15 for the e-liquid, $10 for the doubler and $5 for delivery.)
When you get it home and you've given it a week or more to age properly, take a small dropper bottle and put the same amount of e-liquid and doubler into the smaller bottle. Put the cap on, shake it well and add it to your electronic cigarette for
vaping.
When you have used up your entire bottle of e-liquid, you will still have half the doubler left so the next time you will only need to buy the e-liquid. (You could buy the 4 ounce doubler instead of the 2 ounce one. It has enough to turn 4 bottles of 48mg e-liquid into 24mg.)
Because you are adding equal parts e-liquid and doubler, you just average the strength in each or the % VG
1 part 48mg e-liquid + 1 part 0mg doubler
48 + 0 = 48 divided by 2 parts = 24mg
1 part e-liquid at 10% VG + 1 part doubler at 30% VG
10 + 30 = 40 divided by 2 parts = 20%
1 part e-liquid at 10% VG + 1 part doubler at 40% VG
10 + 40 = 50 divided by 2 parts = 25%
And so on.
