Don't believe the list price!!!! Everyone sells it for about $135.00.
I have not found any place that sells this calculator for $199.00. The big discounters were at $130.00 and $135.00. So even if you are willing to pay extra to have it shipped to you, you may be better off getting it at lets say......WalMart, Kmart, Officemax, Staples, or online here used.

Great Calculator!
I bought this for my son for college. He is majoring in Computer Electronics and Engineering Technology. The calculator has been very useful to him, both in his beginning classes and as his courses become more advanced. It came with everything he needed to use it right out of the box (batteries, cables, and instruction booklet). And he should continue to be able to use the calculator long after he graduates and moves on into his chosen career field. Good buy! Great product!
