Lose Your Amazon Account And Your Kindle Dies

Mike writes: "If you buy a Kindle and some Kindle ebooks from Amazon, be careful of returning items. Amazon decided that one person had returned too many things, so they suspended his Amazon account, which meant that he could no longer buy any Kindle books, and any Kindle subscriptions he's paid for stop working. After some phone calls, Amazon granted him a one-time exception and reactivated his account again. How many people know that when you buy a Kindle, you are really buying a service, and that service can be turned off at a whim? Is it reasonable that the Kindle is so closely tethered to Amazon this way, and that they can invalidate purchases made after the fact?"
