Even with that 15% off, I think I'd still get the EPower from CCV. It's $57 but then you get a free 5-pack of the awesome Ressurector cartos, a free 30ml
juice of your choice, and free shipping. So your gettin about $25 in free stuff, and If you put in "ecf5off" you'll get 5% off the order.
If you decide you want to go with the kGo, I'd check out Hoosier
ecig Supply instead of breezesmoke. It's a few bucks cheaper and comes with the big bore cones instead of the regular. The big bore cones are 1mm wider in diameter and will fit bigger cartos like the XL clearomizers
