I'm probably the most skeptic to ever do a transaction of selling stuff online given the amount of scams out there. I was even apprehensive with GoRoostr to be honest that it took me twice to submit a sale and print a shipping label. But GoRoostr proved to be very trustworthy and legitimate, and they provided a very speedy transaction. I sent my Macbook Air on a Thursday, they notified me upon receipt of the unit on Friday; and then one business day after, as promised they sent me the exact payment of what they quoted me. I highly recommend GoRoostr and their commendable team for doing honest business and efficient transactions.
