While this might be a national issue down the road, Amazon's sales tax is a current issue in Tennessee. I agree with nucanuck, all online sales should be treated the same. The government should not be allowed to pick winners or losers.
Internet sales of goods are not going to slow down anytime soon. We need to be proactive and go ahead and tax these companies before we allow local businesses and brick and mortar businesses go out of business. Amazon does hurt small businesses, but that it not the point here. Amazon is locating business operations to TN and should contribute to the state.
