Graphing Calculators on Amazon

Amazon offers used TI 84 for $42.95.  There are other TI 84 calculators for a bit less.  However, one has a pressure spot on the screen.  Usually pressure spots mean the calculator is about to die.  There are used TI 83 calculators for $19.85.  These are the prices I pay when I bid on calculators from Good Will.  If you experience a problem you should be able to get a refund or credit through Amazon.  I have had excellent service from Amazon.  One time, I had a terrible time resolving an Amazon gift card I sent my mom.  After several calls, the problem remained.  I went to my account and began reviewing ten or twelve recent purchases.  In each review, I wrote an honest assessment of each product.  I added a note that the item was fine—unlike the Amazon gift card situation which remained unresolved.  A miracle!  Amazon resolved the order.  Happily, Amazon backs merchandise.
