Hey guys, sorry for the painfully obvious question, but I've never had to ship with FedEx before. Apple sent me a box so I can mail in my MBP, which is having audio issues. I'm assuming that all I have to do is pack up the laptop, remove the top shipping label to reveal the return label, and drop the sealed box off at an authorized shipping center? Is there anything else I have to do, or is it really just as easy as it seems? I assume that the return box is pre-paid by Apple so I don't have to pay to ship it.
