Hmm, not sure if this was the correct place for this. Let me formally invite you to Tennessee this weekend. For all of your Clothing, Computer & School Supplies... No Tax is included on the referenced items. Unless you purchase a single piece of clothing that is $100 or over. You can purchase as much (clothes) as you want and not pay taxes. Also, computers up to $1500.00 are tax free. Not sure what most of your tax rates are, but ours is 9.25%. So it can be a big help.
