I live in a state that has an income tax. I also live in a rural area. I often order things on line or from catalogues as that is the only way I can purchase them without extended motor trips. If the companies I do business with require me to pay sales tax, I do. Most, however don't. When the states get their act together and start requiring the payment of these taxes, do you think they will go back the allowed seven years as they do with income tax, or do you feel it will be a "from this date on" sort of deal?
