You could always move to Montana, no sales tax there to worry about.
It would take some research, but I know the IRS has a limit of how much you can sell personally before you are considered a business, and your state revenue service would probably be able to answer that question for the state in which you live. It's similar to selling stuff at a garage sale, craigslist, or on ebay, you don't collect any sales tax there because it's a sale of personal property, not business sales. I think sometimes it falls into a murky area depending on the volume of sales, but I have no real experience in moving that kind of merchandise.
I want to die quietly in my sleep like my grandfather, not screaming in terror like the passengers of his car.
