So I have someone contacted me and offered to sell me his MacBook Pro (Retina, 15-inch, Early 2013) for $400. He told that some keys don't work because of a liquid spill, but otherwise, it functions normally. I thought it's no big deal because I just have to replace the keyboard. ...so he brought it over and the screen has staingate Anyway, I told him that I have to think about it. I thought about asking for a lower price since after replace the keyboard, I am going to have to bring it to Apple to have the screen replaced. I also thought about forgetting the whole thing.
