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!

Both Product and Service are excellent.

I search something and they have it, sent an email about it with instant response and Jake helped me order it in a few mins, product arrived much earlier than I expect and in excellent condition.

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.
