Tennessee passed a law a couple years ago to extortcollect use taxes from Amazon.com due to sales to Tennessee residents. I got my statement for 2011 the other day, and thus was pointed to the state website to settle the matter.
https://apps.tn.gov/usetax How much do I owe? 8¢. And I have to pay using something I don't have now...A CREDIT CARD! (All my Amazon purchases came from gift card revenue.)
This benefits the banks more than it does the state, or even the people the law is supposed to help (small Tennessee shopkeepers). Sheesh.
