I recently sent my old Lenovo laptop to CashItUsed. Their website is simple and their quote matched the payment. It’is a great company to do business with and I would recommend them.
I decided to give it a try even though I was skeptical in the beginning. My Asus laptop was just taking space in my closet and it was time to get rid of it. The turnaround was about a week, at least that's when I noticed money in my PayPal. Very pleased.
I got my money confirmed the same day they received my desktop, and they immediately emailed me to tell me that my money is on the way. I would choose them if you have an old device to sell.
