How are related banners used with promotions?

Question

Documentation of this feature is very sparse. Basically, I want the ability to dynamically display a banner on the cart/checkout pages when a certain product is in the cart. Is this what related banners are for? If not, what is their function?

Answer 1

Banners and promotions work as such:

• Banners can be associated to Promotions, and displayed only when a promotion is active
• Banners can be associated, via a promotion, to a customer segment

From the Magento EE User Guide:

Related Promotions – This tab includes one grid containing all your existing Shopping Cart Price Rules, and one grid containing all your existing Catalog Price Rules. Select the checkbox next to a Price Rule to associate it. You can associate this Banner to multiple Shopping Cart and Catalog Price Rules simultaneously. If the Banner is associated to any price rules, it will only display when that rule is applied (the price rule is active and the conditions in the rule have been met). You can also associate a Banner to a Price Rule via the Price Rule page. For both Shopping Cart and Catalog Price Rules, there is now a Related Banners tab in the Price Rule page. This tab includes a grid containing all existing Banners, which can be associated by selecting the checkbox next to the Banner.

And from the section regarding customer segmentation:

Banners – To associate a Segment to a Banner, navigate to CMS > Banners, click Add Banner or select an existing Banner from the grid, and select Specified from the Customer Segments dropdown. This will open a multi-select menu including all existing Segments. You can associate multiple Segments to a Banner.
