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.

Quality Products, Great Prices, Quick Shipping

I am a first-time customer but will definitely purchase items from Underwood Distributing Company if I have a need for their products in the future. I purchased an authentic Texas Instruments battery and replacement charging cord for a TI-84 calculator. The cost of these two name brand products with shipping was still less than the cost of the battery alone through Amazon! Each item came wrapped individually in bubble wrap then placed in a bubble wrap mailer. Shipping was also very quick. I can't say enough about how impressed I have been from start to finish with my purchase.

Perfect!

I placed this order and I believe it was the next day, someone got in touch with me to tell me that they didn't have the specific item in stock to ship out right away, that it would be coming the week after. They gave me the option to keep my order or to get a refund. I told them I didn't mind waiting a bit longer. I got what I ordered, exactly as I had expected it! Customer service was amazing and exceeded every expectation!
