Displaying Comparison Sets supports flexible customization options and dozens of filters that can be applied.

The In Stock filter can be used in Comparison Sets to include certain products based on their stock availability.

The stock availability is provided by the merchant who is currently selling that product.

This includes the following:

• Yes or unknown - This will return products which are explicitly set as "in-stock" or products which have no field containing stock-related information.
• Yes - This will only return products which are explicitly set as "in-stock".
• No - This will only return products which are explicitly set as NOT "in-stock".

To configure your Comparison Set to only show products which are explicitly set as "in-stock," click Add Products.

Then, select the In Stock field and set this to "Yes or Unknown."

Now, only products which are explicitly set as "in-stock" or products which have no field containing stock-related information will be returned.

To take this a step further, select "Yes" for the In Stock field.

In this case, only products which have been explicitly set as "in-stock" will be part of your Comparison Set.
