This offer is only for those with a Kindle Fire with Special Offers (KFSO).
From the home page of your KFSO, swipe the top menu to the left until you see Offers, then press/click in order to see the current offers. At the bottom, you should see the offer for 30% Off Select Kindle Styluses & Stands. Click on the offer, then on the orange button to add the credit directly to your account. It's nearly instant and the next screen offers to take you to Amazon so you can spend that credit away! If you miss that screen, though, don't worry - a document about the offer will appear on your home page. You must sign up by October 28 to get this promo discount.
Choose one or more Kindle Accessories that are both shipped and sold by Amazon and order away. From the wording on the offer, you can use one-click and have multiple orders, up to the $30 total discount allowed. This credit expires November 4. Limit one per customer and one per device.
The stands are already 25%-33% off list price, so your discount will be off the shown price (a net discount up to about 50%). The one from Belkin looks like it would be easy to pack and use when not at home and I am tempted to get a new stylus that matches my cover (with everyone's here being a boring black, it's easy to lose track of them).
