After reading some of the reviews on here, I was skeptical about working with this company. I had a TI-84 Graphing Calculator with the lid and the cord (still with the tie on it, because I never used it). They gave me an immediate estimate on their website, and sent me my label. I printed my label, packaged my calculator, and dropped it off at the post office, as instructed. It took just under two weeks to receive email correspondence from them, stating they had received my calculator, and the next day received email saying that it had been inspected and processed, and I was just waiting for my payment at this point. It took 3 days for the payment to be available to me via PayPal, and I cannot tell you how completely opposite of an experience I had then expected. I was expecting to wait forever, have a headache to deal with, multiple phone calls, etc. but instead it was easy, quick, and efficient for me to sell my calculator to this cash4cals, and I would absolutely use them again, as well as recommend this company.
