I noticed local.amazon.com have for the next two days a free (need credit card to claim) voucher for 30% off Kindle accessories.
I've posted in forum because I haven't tried the voucher yet and it also mentions "Ships only to U.S. addresses" which I'm not sure it means the voucher or the accessories brought from Amazon.
