The Funnel Override Settings allow you to individually override the default settings for each individual product within your sales funnel, including the ability to change the landing page URL or price, without having to create a completely new product in your campaign.
To Override individual settings, go to Funnels > Edit.
Then, select the product in your funnel you would like to override settings for.
Insert a custom landing page for each product in your funnel, which will override the existing default Landing Page URL that you entered on the Product Settings page.
Choose a custom price for each product in your funnel, which will override the existing default price that you entered on the Product Settings page.
