Failing that you can still do an exchange not a refund. Just make sure that after you send out the replacement you call CS and get the file noted that a replacement is being sent INSTEAD of a refund. Have the reship tracking number ready and, as they have done for me, they will close the case without a refund once the delivery is confirmed,.
