One thing I don't see mentioned here is the illegal tobacco market due to high taxes. You can get cigs from Mexico, or a low-tax state, say, and re-import them into a high-tax state. This is one of the braking factors on tobacco taxes. It applies to any market -- if the taxes are too high, people will cheat the taxes. Edit: I see the first link by @munin refers to a Virginia-to-NY cig smuggling scheme.
