This offer is only for those with the either a Kindle or Kindle Touch with Special Offers (those who get their Special Offers on a Kindle Keyboard won't see the offer at all, even if there is a non-special offer Kindle or Kindle Touch on the account).
Get 30% off a Timbuk2 jacket for your Kindle or Kindle Touch
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 February 16.
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 March 16 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.
If this offer is run like previous ones, it pays to grab any cover you want early, rather than late. Once they run out of a particular style and color (and I already see three color choices that are sold out), then they are not replenished during the sale. Those that wait, end up with less selection (usually the more expensive or less popular models). One interesting looking choice I see is the "Dinner Jacket" style, which has a pocket on teh front to hold your license and a credit card or some cash (or a hotel key), eliminating the need for a purse in some cases.
