The return policy is pretty much the same as anywhere else - you have 14 days to return it. You can open the box, use it and if you decide that you want to return it, you hit the button on the order page, pack it back inside the box, stick a sticker that you print from the email you receive from Apple and give it to DHL/UPS/TNT delivery man. When Appe receives it they return the money to your CC (depends on your payment method).
sweet thanks. gives me time to try out this one while i wait for the space gray and eventually settle for one
