Seems the places around the Charleston area are a buck or two higher for tanks and such, but the hardware (batts/mods) is interesting. The cheap hardware is insanely marked up, while the expensive stuff seems to be close to the market price. Doesn't take a rocket scientist to figure out where they make their money...
Have you been to the new place over by Walmart on Dorchester that sells MyStart juice? $6.50/10ml doesn't seem too bad, didn't look at component prices tho since I'd just gotten in my Kanger evod kit.
