Comparison Sets are used to showcase a single product across multiple merchants.

This provides insights into where a product is available, the price each merchant is selling the product for, and more.

When adding Comparison Sets to a post or page, duplicate products can easily be removed from the Comparison Set.

For example, a merchant may offer multiple variations of the same product, the same merchant might be listed across multiple affiliate networks causing the merchant to appear twice in the Comparison Set, etc.

In these instances, there are multiple ways to remove duplicates. For example, click Manage Products > Remove Product to remove the Duplicate.

Duplicates can also be removed from Comparison Sets in a more automated way in the cases where new product become available in the Comparison Set and you want to be sure duplicates are excluded by the fields you set.

To do this, click Add Products.

Here, you can add the Exclude Duplicates filter.

This will allow you to automatically exclude duplicates by fields including brand, price, sale price, merchant_id, direct_url, image, thumbnail and more.

The duplicate result(s) will then be removed from your Comparison Set.
