I find this discussion very curious. There is a company just outside Atlanta, Georgia, that transports billions of tickets across state lines throughout the US. The company is Scientific Games and they supply scratch tickets to almost all the states that sell scratch tickets. I guess they are breaking federal law. What a joke.
My advice. Keep mailing the tickets. Just don't try to resell for profit.
