I display several laminated copies of this sign around my library during the book fair. It has been a HUGE help! Whenever a student asks "how much is this with tax?", all I have to do is point to this sign so they can look it up. I also lay out calculators so they can figure it out themselves if they choose to do so. I live in Tennessee, so I calculated the tax using our 9.25% tax rate. Enjoy!
