If you have a Kindle with Special Offers, be sure to wake it up and check the Special Offers page today, as there are two new deals. Turn on your wireless, click Menu, Sync & Check for New Items, then on View Special Offers after the sync has completed. You should see this new offer:
Save $10 on $20 of Kindle Accessories from Amazon.com
Click on offer, then click on the link on the offer page to sign up and get an email with the promotion code. Sign-up for this offer expires on July 19.
You'll get an email (right away), a link to the Kindle Accessories page and a promotion code to enter at checkout. Once you have the promotional code, you have until August 19 to complete your purchase (full details here). 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).
Once again, this offer can be used more than once per accounts, so long as you have more than one KSO registered. Just click on the ad on each device to receive the individual promotion codes via email.
If this one works like the last one, you'll probably be able to use the code even if the Kindle Skin or other accessory you want is a penny (or even a nickel) shy of the $20 minimum. It's easy enough to check - put the item into your cart and start checkout. Enter the promotion code and click on Apply - check the summary at the right of the page to see if it was reduce by $10 (you should see "promotion" and -$10.00 and a reduced total). You can even stop at this point, go back to your cart, shop some more and come back, as the promotion code isn't used up until you actually check out.
