Wow. I'm amazed at the response to this thread. Thank you to a great community!
So far it hasn't saved us much money because I've accumulated a small collection of 510s and eGo units that'll cover us in case of dead batteries and such. Also I've bought a couple units for friends. Next month I plan to buy some leaf tobacco, herbs, and pharma-grade glycerin and PV. I know I can make my own juice, it was just a matter of learning how.
You guys have all been so great, I have to say I'm really touched by the response of the vaping community. I joined this forum for information. I never expected kindness. What can I say? Hopefully I can give something back.
