Comment Fact: Amazon has physical presence in 19 states (Score 1) 639
Differing opinions are fine, but let's have a reality-based debate. No state is attempting to unilaterally tax Amazon unless it has buildings and employees in the state.
The corporation has real facilities you can walk into in 19 states. It collects sales tax in just five of these (two are in states without statewide sales tax). See http://www.amiba.net/resources/news-archive/amazon-nexus-subsidiaries for the list and documentation.
