The Frequently Bought Together module lets you create discounted product bundles with items that are frequently purchased together.
You can create both percentage and fixed discounts for your bundles and add as many bundles to a product as you want.
Merchant Pro displays the discounted Frequently Bought Together bundles in eye-catching widgets on the WooCommerce product pages:

As you can see in the above screenshot, Merchant Pro automatically calculates the monetary value of the percentage discount (i.e. the first widget shows 7.00 $ instead of 20% as the discount value).
Merchant Pro also automatically applies the bundle discount on the Cart page, plus displays a short notification under each product to remind the customer that they’ll purchase the product for a discounted price:

Now let’s see how to set up and configure Merchant Pro’s Frequently Bought Together module.
1. Open the Frequently Bought Together Module
Open your Merchant dashboard by clicking the Merchant menu in the left sidebar of your WordPress admin area.
Find the Boost Revenue section, then click the Frequently Bought Together module to open its settings page:

2. Configure the Settings
On the admin page of the Frequently Bought Together module, you can find three groups of settings:
- Settings – Here, you can configure the location of the Frequently Bought Together widgets: you can show them after the product summary, after the product tabs, or at the bottom of the page.
- Text Formatting Settings – These settings let you change the text strings of the Frequently Bought Together widgets, including the title of the widget, the price label, the ‘You save’ label, and the button text. You can use the {amount} variable to dynamically calculate the discount value using the product options (we’ll see how to set up the product options in Step 4).
- Style Settings – Here, you can customize the design of your Frequently Bought Together widgets, including the text and background color of the Plus icon and the border color and border radius around the bundled products.

Once the settings are configured, click the Save button in the top-right corner of the page.
3. Enable the Frequently Bought Together Module
Now, you can activate the module. To do so, click the Enable button at the top of the page:

4. Create Your First Product Bundles
You can create your Frequently Bought Together bundles on a per-product basis. Once the module is activated, new product options will appear on your WooCommerce product pages.
Go to the Products > All Products menu in your WordPress admin area and open the product you want to create the bundle for.
Then, scroll down to the Merchant Product Options section, which includes the product-related options of your activated Merchant modules.
Open the Frequently Bought Together tab and click the Add New Bundle button to create a new bundle (you can choose between a percentage and a fixed discount).
Then, fill in the Discount Value and ‘Select Product(s) Included In The Bundle’ fields of each bundle you want to add to the product:

Once you’ve added all the Frequently Bought Together bundles you want to show for the product, scroll back to the top of the page, click the Preview Changes button, and if everything looks OK, click the Update button to update the product.
