GBTopcalcs is legit and awesome! Highly recommend :) Topcalcs made the process of selling my used calculator easy! I appreciated the timeliness of receiving a shipping label for my calculator and the ease of just putting it in the mail and sending it. I received all the money it was worth and would do this again! I highly recommend using this service :)

GBDisaster 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

GBI 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
