I love to build my own coils. In my early days of vaping I would get that oh crap my atty is getting weak feeling. Then realizing I only had one replacement head left and mail would take a few days or more to arrive. No b&m in this area. I was forced to start building my own. After building a few successful builds that dread turned into a cool my coil is going bad, time to build a new one. She probably doesn't build or doesn't know how to build besides rehashing a sale is her business. If you don't know about building she would also have to answer questions about ohm's law batteries etc.. Do you really want advise from her on these things? There's not much money in kanthal and cotton I guess but a few more $'s in new replacement coils. Her loss
