I got a nice promo idea on the Kindle store called countdown deal.
You decide to discount your book for few days, where the first one is the most discounted and then it has small increases, day by day, until reaching the original price.
Only after it was approved I found out that:
- It works only on the .com
- It doesn’t display the discounted price but the original. Once added to the cart, upon viewing your cart, you should see a discount.
