I know this might be a stupid question, but I am thinking about going to the Apple Store today to buy me a Macbook. Do you think I should open it in the store to see if it should have any pixel errors? What else do I have to check then? Or would it be better to order it online? Do you have any other important advises? Furthermore, I'm a European student currently living in America, do you think that they will accept my international student identity card (ISIC), or do only American students get the educational rebate?
