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

you guys take way longer than 48 hours… you guys take way longer than 48 hours to process my payment

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!

Upgraded my trade in Value! They upgraded my trade in value due to a better condition than I reported. Who does that?! They were quick to process my trade in and paid out quickly as well. I'll definitely recommend this company to anyone wanting to sell a calculator. Definitely a company that runs off integrity, something that is hard to find these days. Thanks again!

I dislike how long it takes for them to… I dislike how long it takes for them to payout they received my package @11am Tuesday Didn't comfirm they got until Wednesday 1pm and then they didn't payout until Friday 5:30pm all the stuff was brand new I don't understand what took them so long to process my buyback there competitor sellyourcalculator.com processes the buyback the same day they receive it and they pay it out by the end of the business day the only thing I like about your site is that you have cash app as a payment option
