I've had my Volt for 1 week...smoke free for 5 days (was a 3 ppd guy). My wife of 37 years just got her kit 2 days ago (after seeing my success)...and I got us each a variety pack so we could settle on our favorite flavors. Now it's time for my next order and I figure we need to add a couple of batteries each month so that we have some spares. My wife has a black and a red now. So I ask "what color battery do you want." Now with her starter kit order it was "I don't care." Obviously she cares NOW. Her answer this time was "do they have gray? That would go with my gray outfit." OMG...we are now accessorizing...this is out of my league. "No dear there is only chrome." "Well, what colors do they have?" OK, I'm a guy. I have no idea what the difference is between raspberry and purple...between blue a sky blue...gold and copper. I am also totally confused by teal, mauve and taupe, but that's another story. So I just handed her the computer...and she started selecting..."Blue will go with that outfit...I could use a purple...and a..." This is going to be way more expensive than I thought. Oh well, at least it's just $15 batteries and not Gucci and Ferragamo.
