This offer is only for those with the new Kindle Touch.
Save 50% on select Kindle covers at Amazon.com
Click on offer, then click on the link on the offer page to receive an email with the promotion code. Sign-up for this offer expires on November 23.
You'll get an email (right away), a link to the Kindle Special Offer page and a promotion code to enter at checkout. Once you have the promotional code, you have until December 24 to complete your purchase. Like previous offers, this one requires you to use the full checkout process in order to enter your promotional code. Also, like all Amazon sales that use promotional codes, if you have a gift card balance, you must use it for the payment (if there is not a sufficient balance, then you can pick which credit card or other payment to use).
Limit one offer per customer and per device.
I didn't see this one earlier today and it is only on my Kindle Touch (along with an ad for Dove Subscribe & Save and the 10 points for digital purchases for Amazon Rewards members, which I don't see on the other devices, either). The selection on this offer is less than originally available on the previous Kindle covers offer (looks like Amazon has sold out of a number of options).
