I was admittedly skeptical of this… I was admittedly skeptical of this being a scam. I’ve never worked with selling back calculators, so I was pleased with being able to get a free shipping label printed out and I could easily send it out. Everything was transparent with timing (tracking on the package itself) as well the receiving of payment. Grateful for a good experience

Customer Satisfaction The first TI 83-Plus Lime Green edition I really wanted and ordered, was sold at a great price to begin with. When it arrived, the screen had a permanent pixelation in the top right-hand corner. I followed the return process and emailed them Friday. Since Monday was a holiday they didn't respond till Tuesday and set me up with a Blue TI 83 Plus not the one I originally wanted but hey it works 100% and at a great price! With the help provided and the short turn around I gave this a five-star rating because not only did they honor their word on the warranty/return policy. They helped me out without any hassle or grief, exchange was simple and included a return shipping label. Thank you Topcalc for taking care of me! I will definitely recommend to my classmates!

Disaster Well said. I sent my calculator in at the beginning of January.. still have not been paid. They have the wrong paypal written down. They keep saying its sent. Sent to where?? U have the wrong pay pal.. I can't speak to anyone on the phone. I have called. No one answers. I leave voice mails. This is in a small building inside of another company. I have emailed and emailed nothing but, hey send us ur device.. They have my device now what. Seems like maybe this is a scam. I had a Texas t 84 now. I want to speak to a live human please
