Take it to a Genius Bar and be super friendly and polite. I had my MacBook screen crack and it was out of warranty. They told me they were going to have to charge me and I was nice about it. The guy then came out of the back and said they would do it for free. Was super nice of them and I don’t know why they did it. A year later when I cracked it again, I had to pay. The adapter cord keeps getting between the screen and keyboard which cracked it twice, so I am super careful now.
