Microsoft - the manufacturer of the RRoD-prone Xbox 360 - has confirmed to Joystiq that it's discontinued its policy of providing a prepaid box with shipping label, more commonly referred to as the "coffin," for all Xbox 360 repairs. As of May 26 the policy was discontinued "in an effort to expedite the repair process." Customers will have the option of receiving an e-label to slap on the box they ship their bricked consoles in, but the days of the "coffin" are now over. A Microsoft spokesperson tells us, "Customers can now ship their consoles themselves using an e-label provided by Microsoft and do not need to wait for an empty box to be shipped to them."
