More and more, kids need a graphing calculator for Math. Try Good Will online. I recommend bidding on TI 84 or TI 83 graphing calculators. Be sure the calculator powers on. The stores on Good Will usually have pictures with the calculator powered on. Avoid listings that are untested. Check the shipping cost. If your total cost for a TI 84 calculator is less than $40, you have a bargain. Don’t pay more than $25 for a TI 83. I have bid on eBay, with very little luck. I bought another used TI 84 on Amazon, which was a terrible deal. The calculator was gritty. It did power on; I’m using it as a digital thermometer. I have had the best luck at Good Will. Happy Hunting!
