I brought a 13' air (i7/8g/128g) 1 week ago, and there are two dead pixels on the screen. I dont think I can stand it. There is no apple store near my city, however i find a bestbuy within 30KM. Can I return it there? Because I heard that the bestbuy also sell apple products or I have to send it back to apple use fedex? Thx guys.
