PLEASE READI bought a pre owned MacBook from IT Supply Solutions. They gave me a great deal on it, and even backed it with a 3 month warrenty. After a week, I found out that there was an issue with the IO Board, something IT Supply Solutions didnt test for before they sold it to me. A $310 fix through Apple. I spoke with Scott, their Senior Account Manager, and he replaced it for free, and even upgraded me to a newer MacBook because of the inconvenience. This company GENUINELY cares about their customers, and I highly recommend you give them a call.
Awesome place
