I had my graphing calculator to sell and this company seemed liked a viable option. I did some research, and reviews for the site seemed to be hit or miss. I took a chance and definitely lost on this one. I made phone calls and a number of emails and I was never sent any compensation for my calculator after I had sent it in. I spoke with a few different people and there always seemed to be some confusion about my case and I had to explain my situation several times. Ultimately I realized that I was never going to be paid so the best thing I could do would be to warn others.
In today's virtual marketplace there are several avenues for selling used goods. I would highly recommend not using Cash4Calcs. They ripped me off and a cursory search of their review listings will show that this has happened to others.
You've been warned!
