Used Calculator

Hey y'all,

I'm preparing for the FE a couple years early by getting my muscle memory accustomed to an NCEES-approved calculator. See below:

• Casio: All fx-115 and fx-991 models (Any Casio calculator must have “fx-115” or “fx-991” in its model name.)
• Hewlett Packard: The HP 33s and HP 35s models, but no others
• Texas Instruments: All TI-30X and TI-36X models (Any Texas Instruments calculator must have “TI-30X” or “TI-36X” in its model name.)

Anyway, in the spirit of being a broke college student, I was looking to save some money. Where are some good places in Houston to save some money on used calculators? I'm not entirely sure what place would even sell calculators, first-of-all, but it was worth a shot.

I appreciate y'all's help. tysm.
