Ok just got off the phone with a very nice lady at X-Tra, she said the only two flavors that contain oil are orange and lemon, everything else is artificial flavoring. I suspect these are different flavor molecules combine to represent an actual flavor. BTW she is a smoker and has never heard of e-cigs, so she will be checking into them

I offered to write a review of their flavors if they wanted to send me some samples, so I have to talk to Brian tomorrow to do that. She also said there was a possibility to get a more concentrated flavoring, but I would have to talk to Brian.
So I will be talking to Brian tomorrow
