AmazonLocal offers a Voucher for 50% off an Amazon Kindle Accessory Purchase at Amazon for free. (A maximum discount of $50 applies.) That's the best such discount we've seen on Kindle accessories since September, when we saw a voucher good for 60% off. (We also saw 40% off three weeks ago, but a maximum discount of $100 applied.) The credit can be redeemed on qualifying purchases from the Kindle Accessories Store. Several exclusions apply. Deal ends January 4 at 3 am ET.
