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!

A+++ Selling Experience Quick selling process and when my Cash App payment didn’t process; they immediately sent me the funds through Zelle. Definitely a good partner to buy & sell from!

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

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!

You will not regret buying or selling to these capable people I have to say I was a bit skeptical when I let go of one of my graphing Calculators go with only the word of an acquaintance to depend on for worthwhile compensation delivered in honest and ASAP fashion. I had accidentally had a capital letter in my cash tag (100% the fault of the other person sending his object in the same package.) I obviously grew disheartened after the payment day came and went. This company immediately made it wright and I was done. I would do it again in a heartbeat
