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!!

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!

Fast, Easy, Highly Recommended! Fantastic transaction! Took 48 hours from clicking Submit Sell Back to getting paid via Venmo. Ymmv depending on ship times. Highly recommend over the hassle/fees/time consumption of eBay. Will definitely use again if the need arises!

I got the highest value available… I got the highest value available online for my almost new calculator. The shipping process was so easy, everything went so smoothly, simply awesome!

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!
