If you live near an interstate you might try some of the gas stations.
I stopped at a station the other day and they had a display of small bottles of juice (maybe 5 or 6 drams) and I asked what those were and she said they were tobacco flavorings. Must have been 15 or 20 different flavors. I think she was confused, I'd never heard of anything like that, and asked if it was e-juice. She didn't know what I was talking about. Was in a hurry so didn't pick one up, I'll stop over the weekend and see what it is. Thats the first time I had seen it.
