I notice on the SI Web site that the starter kit is $29.95, but if you buy all the items separately, it's 10 cents cheaper. Also, I attempted to get my daughter interested, and I sent her a disposable, the same kind I tried at first. That was about $13. Is there a way to make a disposable (batt & carto of the flavor choice) like the ones I ordered for about the same price? If so, a lot more beginners might get into it, since I think the Volt flavors allow more taste choices, and the RY4 tastes a lot better than what I ordered from the disposables company. You could make the disposables in the most popular flavors at all nic levels. Would that have enough clientele?
