An Examination of Graphing Calculator Prices on Amazon
If you’re like me, you’ve noticed that prices on Amazon seem less stable than those in brick and mortar stores. There have been times I’ve visited Amazon for a specific product, noted the price, and when I checked back in two days later, the price had changed significantly. Check again a week later, and it’s different still. Until recently, this was just anecdotal for me. I wasn’t sure if what I thought was true was really true.
