The main reason I've enjoyed purchasing from FrontierVapor is the man who runs that site. Alexander is such an incredible guy and provides the best customer service I have ever received. I started out as a newbie and had no idea what I should be buying or doing when I got into e-cigs and vaping, and he has delightfully answered every question I have asked, and provided me with samples and coupons to help get me started. He has been incredibly active on Reddit under the username /u/FrontierVapor and explains everything clearly and concisely. His site also accepts Dogecoins and Bitcoins, and I made my first purchase in Doge and the transaction went through perfectly. I highly recommend purchasing from FrontierVapor for the customer service alone, or even just having a chat with Alexander because he is an incredible guy.
