Myself, I would like to get a couple extra batteries, cartridges, atomizers and covers. Where can I find the best price? by the way, there is a huge thread here: http://www.e-cigarette-forum.com/forum/general-e-smoking-discussion/340059-joyetech-eroll.html on the eroll for those interested. I just find the thread too long to find answers to specific questions. Really this product should have it's own sub forum.
