I was wondering if there are any ways to get replacement screws for the bottom casing of the unibody Macbook Pro 13". I have one missing, and three of them are slightly damaged, but I want to prevent it from becoming more damaged to the point where I can't get it out. If I go to the local Apple store (there is one in Shibuya and Ginza) will they give me the screws for free or do I have to pay a fee? I don't mind paying for it as long as it's under $15. For your information, mine is not currently under warranty. It's a mid-2009 Macbook Pro 13".
