I ordered this MacBook Air for a customer but when I opened the box it had a banged up corner on the screen which is only cosmetic and doesnt affect the screen at all so for that Im going to sell it and order the original customer another one. Im taking $50 OFF for the banged up corner. It does come with a 90 day warrantyMacBook Air 133 MD760LLBIntel Cored i5 4th Gen1.40 GHz Processor4GB of RAM...
