If they are selling across state lines and over the internet they aren't supposed to be collecting state sales taxes anyway.ok . long story short . you find a so called legitamite business cunducting business selling high end product and not collecting sales tax and also you find out the so called business is not even registered in there state and more or less they are a fly by night operation.... now the questions is what do you do as a law abiding citizen ? can this be reported to there local law or ?
think about it . if you owned a legit business and paid your "dues" would you be mad ? especially if the other company was intruding on your teritory
