To answer a few questions that were raised (I'm only a couple miles from one part of one of the reservations)
1. You used to be able to order cigarettes online. It's now illegal to send cigarettes by mail. That's a very recent change. It was aimed (obviously) at shutting down the Indians, particularly the Seneca Nation who controlled about 80% or more of all online sales. Basically, that law will all but stop their online businesses.
2. NY "plans" to tax cigarettes purchased on the reservation. HAHAHAHAHAA! HAHAHAHAAAAA HA HA HAA! The Indians manufacture several brands themselves. So, NY can't go after the suppliers to keep them from selling to the Indians. Strike one. NY has ZERO sovereinty on Indian land. The Senecas can do whatever they want. The *only* way NY could tax those cigarettes is to put up road blocks and searched everyone's car leaving the reservation. Legally, it's a big circle jerk in Albany where they're just posturing so they can say, "see, we tried to make them play fair! Sorry local small business owners competing for cigarette sales."
