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!!

Topcalcs is Top Notch!!!!! I sent a graphing calculator to this company and they had quoted me a buying price. When they received it they sent another offer increasing what they wanted to pay because the condition was better than I thought. That, to me, is the definition of a company being honest and having integrity and stellar customer service and should be recognized! Great job Topcalcs!

Super fast and easy Super fast and easy; priced my calc and got the labels plus your free shipping offer made it feel legit and I got my PP that same week.
