Well, maybe I'm just different, or maybe it's because I'm from Pennsylvania Dutch country... Or maybe I just get it from my dad, I dunno. But I like to save money and find the best deal I can as much as possible. Volcano sells their 10ml bottles for $8.99. That's about 90 cents an ml. Vapor Renu sells 30ml bottles for $6.99. That's 23 cents an ml. Volcano's juice costs almost 4X as much and gives no options for pg/vg mixture, throat hit, flavor intensity, or options for liquid vitamin c, ginseng, milk thistle, or vitamin B12. Vapor Renu has all of these plus a crapload more flavors. I mean no disrespect to those who like Volcano, and I'm not trying to badmouth them either, but I would never buy juice from them. I like 100% VG, and I can't justify paying the same amount of money for 25% of the volume that I could get. A box of cereal costs like 3-5 dollars... Would you honestly spend 12-20 dollars on a box of cereal? Or a dollar on a pack of wrigley's gum? 2.50-5 dollars on a pack of bubbalicious? What about 20 - 40 on a pack of cigarettes? If you could get all of these things for 75% off of the prices I just mentioned(and you can, as all I did was multiply everything by 4), would you pay those prices? I highly doubt it. Volcano hasn't done me wrong either, but neither has vapor renu or totally wicked. A buck or two saved definitely adds up, but you're not saving anything if you pay more than you have to. I'm nowhere near the penny pincher my dad is, but holy crap. I just can't justify buying much of anything from Volcano. PCC, drip tip, spare L88B parts... that's it.
