I contacted Amazon regarding a malfunctioning Kindle. The Kindle was just outside the warranty period. However, I was offered a replacement Kindle. The new Kindle was delivered within 48 hours. The postage to return my old Kindle was pre-paid. I am very impressed with this standard of service. Of course, it does mean that I am able and willing to continue to purchase Kindle books. I would not have done so if I had not received a replacement Kindle.
