I know what you mean about cost; thats why mt sister hasn't stopped analogs. so this is what I did...I packed up my old starter kit which was an ego-t starter and put all the extra tip tanks covers and three bottles of e-juice and some carto's and gave it to her, and told her to use it and get off those d**n cigarettes.I showed her everything she needs to know about how to use and care for it. hope it works.
I just did the same thing for my sister in law this weekend. If there ever was anything you wanted to Pay It Forward, it's vaping stuff.
