Just because Amazon is a large corporation doesn't mean it won't hurt them to have to figure out the tax laws for all the different counties/cities/and state level. Not only that, but why should Amazon be forced to file taxes in 50 states. How does this ruling affect other much smaller companies? If I had an affiliate program would I now have to start taking money according to California tax law even-though I am located in Arizona?
