There's an obvious workaround for the next 2 years at least. B&M's that take the initiative to get their tobacco license can order and sell whatever they want. Custom order and pick up in the shop. B&Ms may have a nice opportunity in front of them. They can just be a middle man and make a slice. They collect upfront too. Organized group buys could become popular too.
Yeah it sucks that people in states that prevent internet won't be able to get it delivered to their door. But I personally don't see them being denied the ability to get what they want. It will just cost more and not be as convenient.
My state borders WV and they just voted not to tax ecig sales. I doubt they will ban Internet sales. I have friends in WV. Inconvenient yes...impossible no.
After the 2 year window all bets are off...
The fly in the ointment is a required photo ID by the FDA rules, not sure how that is going to work with online sales yet, TX already requires either a photo ID or signed legal document and confirmed CC in your name for all online sales.
