GBI 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

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 :)

GBPlus more! I ordered a total of 11 calculators so far and their condition was excellent. They all worked and getting batteries was a bonus. Customer service was excellent. I will be buying more. Thank you.
