If you want to (temporarily) stop using your Amazon Repricer(s), you can deactivate the Repricer in the Amazon API in Channable:
Navigate to APIs > your Amazon API > Settings.
Change the Repricer status to "Inactive" by clicking on Deactivate repricer.
Now the Repricer is deactivated and it will no longer reprice your prices.
The Repricer should no longer be listed under "active repricers" in your current usage. You can now also remove the Repricer as an add-on from your subscription. To learn how to do so, read this article.
