I noticed this a while ago... I don't see how they get away with no sales tax, being that they do business in most of the western US. Unless the residents of those states DO pay sales tax?
And just in case anyone is interested in Polk Audio speakers from the Good Guys, Polk has been dropped. This was first mentioned on the Polk Club forum, and I confirmed it last nite speaking to a Good Guys salesman. Polk Audio is no longer on the Good Guys website either.
