CashIUsed is a great way to go! They explain everything very clearly so that you can get an estimated quote and ship your all in one device to them. Will definitely use them again.
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.
The entire process from the quote to the final transaction makes it so easy to get cash for your laptop. I highly recommend this business if you are looking to cash in your laptop. I would highly recommend using them! Would do business with them again.
