SELLING Macbook Pro 15in w/ Retina Mid 2012 $1200

I recently got a new computer so I'm selling my Macbook Pro with Retina Display. 15 in screen, intact with two very small, almost unnoticeable discoloration spots. I've tried to include them in the pictures. There are a few faint cosmetic scratches on the underside and the left edge. There is also a small ding on the front edge of the lid.
