The answer is different to an experienced vaper. I'd want 30ml on hand. say 10ml of my 3 flavors. Basically, enough to get me until the postman delivers the next batch.
But since Mom is a beginner, I'd want a few more options. Besides the Torque, maybe 1 other flavor. (Malibu, Belgian Cocoa, Mystic, maybe some Tribeca.) Since we don't know what she will like, nor are we sure of the nic level, you might want a selection on hand. Don't worry, it'll probably all get used. I have some juice that I add just a bit as a filler to other juices, sort of stretching it out.
I wouldn't worry too much about the money right now. She was spending about $25 a week on cigs. Once it all levels out, she'll be using 10, maybe 15 a week. Since you'll want to buy from Halo, you want to take advantage of the reward points, so make sure you buy $20 of hardware (if needed) and $20 of juice. (Remember, the reward is for each $20 spent after discounts and before shipping. The code ECFTEN2014 is only for 10% off juice).
Let's hope she likes the mini tank. They are much easier to refill than a carto. And for batteries? I'd try to have enough for her to last at least a day without recharging. 2 bats might be cutting it tight. A third would give a nicer margin. And maybe she'd like one of a different color.
And I know how easy the automatic G6 batteries are to use. But they don't have much capacity. If Mom could learn the one button to push while vaping, this opens up better possibilities. She could get a Triton battery. a 900 or 1300mAh Triton battery isn't much longer (yes, fatter, a half inch diameter vs the thinner G6) and would most likely last her all day. (You'll need a Triton charger, the G6 charger isn't compatible).
Last but important. I wish you strength, luck and good wishes. I admire what you are doing for Mom. It is challenging, difficult and a sacrifice. I applaud your good efforts. Feel free to send me a PM at any time with questions or problems. I do pray for her success in this life change.
