The Pricing Tool doesn't just show you data, it also allows you to act on it by setting rules.
By clicking on the "Settings" button on the top right of your screen, you will open up the Pricing Rules Settings. From here, you can apply changes to your prices as they appear on the Competitors List.
As seen in the above example, you can set your prices by dollar amount (or percentage), to be below either the average (or lowest price). You can also set a floor that your price can never go below, either a dollar amount or percentage.
In the Test section, you can see how different changes will affect your price.
To queue up price changes, you will have to send products to the Pending table and then push them to finalize from there.
