I just received $60 off any Kindle and found it only works for some people. From what I've read it is $40-$60 off for some people only. Just sign into your amazon.com account then click this link http://www.amazon.com/gp/featu.....d_i=507846
If an offer is available for you it will tell you how much you can get off. I never received an email about this but it worked for me. I just scored a Kindle for $9!! Let me know if it works for you in the comments.
UPDATE: Keep checking back. Amazon is adding the deal to accounts until the end of the day tomorrow (10/29) so if you don't have it now you may get it tomorrow.
