AmazonLocal has their deal back where you can get a Free Voucher for 30% Off select Kindle Accessories. See voucher for exclusions/details/requirements. It should be listed under “All Deals” but if you don’t see it, look under Chicago as it’s there. There’s one day left on the deal.
When you go to use the Voucher, look under the Kindle Accessory that you are buying at several of them also have a Free $2 MP3 Credit going on right now, too. It will be listed under the product info if it’s part of that promotion.
