I recently asked Apple for a replacement on my current rMBP. But I thought it was too much of a hassle because I was told I could not keep my current one until replacement comes. ( I don't want to get a worsen product) They sent me confirmation email from UPS to confirm replacement but I did not confirm it. Now I just been notified that a current replacement has shipped today and is one its way. My current rMBP is passed its 14 day return , when I receive the replacement and decide to return it, is it still possible?
