For the Charlotte area folks
Carolina Ecigs has two brick and mortar locations (both fairly new) in the Char-meck area. One in Huntersville and one in Fort Mill, SC. Prices are fairly competitive with MadVapes (though they don't have quite the selection of apv's, just a few VVs and mechs) and customer service is top notch. They carry halo juices, as well as their own house brand Smooth Vapes. http://www.carolinaecigs.com/#
(EDIT: Retracting my previous statement about the customer service at the MadVapes Charlotte location. Went in again today and service was very good, enough to retract my previous feelings).
