Hi Di, I see this as the #1 header when I go to your site, but can no longer find a way to order them. If I remember correctly it was 5 sets for $95. Is this package still available? I'm working up an order and hoped to include these kits. They're not the most exciting thing on the site but for the last year I've kept some basic BE112 kits on hand to cost out to local smokers who ask me about e-cigs. Once I get them into vaping, I steer them to the forum. Doing this, I've started about 30 on vaping of which approximately 6 kept smoking, 5 managed to completely quit nicotine and the rest switched to vaping. I realize not everyone can afford to do this but if one can, its pretty rewarding to help people kick a deadly $3500/yr habit. At $19, it makes sense for me to switch over to your 510 kits, 510s being easier for newbies to learn to use.
