You got rooked, but it could have been worse. These guys don't seem as greedy as most of them. A lot of us got scammed on our first e-cig, buying from mall kiosks or other web sites. If you can only buy the parts on one site (and no one says what they are compatible with), stay away! Use up what you have, and check out the 510's and or 808's. The site seems to be apart of a network of sites operated by "http://www.greenfootmedia.com/". They are also into "Carswaps" and HouseForeclosures....
The starter kits and e-juice by the bottle will more than pay for it's self in a month or two. Plus you'll have much more selection in flavors, and sites competing for your business.
