You Must manually change your price for each Amazon “zone” as shown below. Kindle Countdown Deals (KCD) only reach Amazon US and UK. We have readers from all over the world, and they all deserve to have a 99c deal. If I find out you’re using a KCD for your listing, your listing will be removed from the promotion.
The above image is from the pricing area in KDP. You want all of them to be the lowest you can price it. Some of the prices above are not the lowest, but that’s because Amazon saw fit to change them without my approval. I’m just finding this out at the time I wrote this FAQ.
