The desire by legislators to tax on line activity (sales, email, etc.) has been in the works since the late 1980s. There should be no surprise in that regard, ie., developing revenue streams. Things that are popular (like tobacco and alcohol) or media events, etc. are generally taxed. And, truth be told, goods sold (USA) from one state to another should include declared sales tax (but the customers never do). This attempt to collect revenues will not go away, particularly in these recessionary times, so expect more of the same. Should it come down to all 50 States enacting legislation regarding affiliate sales what's next for Amazon?
