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!

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!

Paid top dollar of my kid's hardly used… They made a reasonable offer for my kid's hardly used graphing calculator. Return was quick and payment was prompt. I sell online on ebay and craigs list and this was the easiest and most straightforward transaction I've ever had. Thanks Viktor!!
