Graphing Calculator purchase was wonderful

I am a math teacher in Ogden, Utah. We have ordered from Underwood twice now, buying TI-84 Plus CE graphing calculators both times. They were easy to purchase, a great price compared to others, and arrived quickly. No complaints here! Definitely recommend!

Wonderful source for TI calculator add ons

The Ti 84 launchpad board and RGB led board are hard to find new for just a single user and definitely not at such a good price. Prompt shipping and everything arrived well packed. Seriously great source if you are looking for small quantity at great value. Thanks!

Best experience!

I ordered a calculator late Monday night that I needed by Wednesday. I communicated with Jake several times via email and once on the phone throughout the next day. Had my calculator before noon on Wednesday. Every response to me was quick, helpful, and very courteous!! Great company and customer service. I will order through them in the future and highly recommend others to do the same.
