Hi, I think I'm going to buy a refurbished Macbook (Aluminium or Pro), but what is the return policy? If I get it, and I'm not happy can i return it? What if it has a scratch or dead pixels? Can I return it for a replacement? Will it be updated with the latest Snow Leopard? What box does it come in? The apple site implys it will come in the same box as usual.. Thanks!
