I guess it was easier for us because both my wife and I needed to quit cigarettes. While our reason for quitting was health based rather than cost, we were spending about $75/week for cigarettes. Since buying 2 kits for about $50 each, we are spending about $25 per month for e-liquid. Our Clearomizers seem to go on and on, as I clean them now and then with everclear. Same 2 have lasted 10 weeks so far. The cost reduction is a no-brainer. The health benefits are obvious to us. I have had chronic bronchitis since childhood. Since switching, I have not needed inhalers, etc. We were so satisfied with the results that we purchased units for my sister and 2 nieces as Christmas presents. We have absolutely no regrets. (My wife had tried Chantrix, patches, etc with no success.)
My quitting is health based also. I also plan to pass along my cig alike to my Sister in Law to see if she can stop her 3 pack a day habit...I think the initial 'start up' cost blind sided him. He picked the first cig alike he came across that was cheap, not bothering to do any research.
