Texas Instr TI-89 Graphing Calculator $99

This deal has ended.

Back-to-School Season is about hit in full force and Amazon has cut $40 off their price on one of the staples: the Texas Instruments TI-89 Graphing Calculator is now just $99.99, despite most other stores selling it for $150 or more, before shipping and taxes. Amazon's shipping is free and they only charges sales tax to the few lucky souls living in KS, ND and WA. Most other models of Texas Instruments Graphing Calculators are also available.
