10 THINGS ALL AUTHORS SHOULD KNOW
1. How to Contact Amazon to Price Change
There may come the day when you want to change the price of your eBook to 0.99 or to free but you're unable to do that on your KDP dashboard. So how do you do it? Do you go to your book's Amazon page? Many used to reply on the "Tell us about a lower price" link under a book's product details, although that was very insufficient and could take a long time to hear back, if you ever did. In fact, that option is no longer there.
So, how do authors change their eBooks' prices to 0.99 or free on Amazon?
You do it through KDP's Contact Us page: https://kdp.amazon.com/en_US/contact-us
Beneath "How can we help?", click on "Pricing" and then "Price matching." Then click "I still need help." You can contact them through email or phone. Phone may be faster, but I always did email because I hate talking on the phone. When you choose to send an email, make sure you have the ASIN for your eBook in the Kindle store and the competitor's URL links. Always specify what the price is listed as and what you want it to be instead.
TIP: If you are changing the price permanently or even for a specific amount of time, always check back to make sure Amazon hasn't reverted it back, because they like to do that and it is maddening.
You can also ask them to price match on all Amazon marketplaces (UK, DE, etc.)
