The Product Add-on feature lets you boost sales and enhance customer experience by offering related products at a special value when customers purchase a main item. This is a powerful tool for increasing average order value and promoting complementary products.
With Product Add-ons, you can:
This feature is ideal for promotions, bundles, seasonal offers, and driving upsells without the need for complex configurations.
Go to the Kefi Bundle Builder homepage and select the Product Add-ons. Click “Select”
After you choose to create a Product Add-on, you'll be redirected to the Content section. This area is divided into four key sub-sections that help you customize how your bundle looks and works on your store:
1. Bundle Info
This section lets you customize the title of your bundle, which appears on the widget customers see while shopping. You can use this field to create an eye-catching or descriptive title that communicates the value of the add-on offer—like “Complete the Look”, “Bundle & Save”, or “Recommended Add-ons”.
2. Product Setup
In this section, you’ll choose which products in your store will trigger the Product Add-on offer. You have three targeting options:
In this help guide, we've selected the Specific Product option and added a product from the list as an example.
Once you select the product category-for example, Specific Products-you'll then be prompted to choose the Add-on Product you want to offer alongside those items. This is the product that will be shown as an optional add-on in the bundle widget.
For instance, if you're running a promotion to offer 20% off air pods with any I-phone, you would select a specific product (Iphone) and then choose the air pods as the add-on product.
This setup allows you to pair relevant items easily and encourage customers to add more to their cart.
Show Swatches - You can also display product variants-such as different colors, sizes, or styles-by enabling the Show swatches option.
This allows customers to view and select from the available variants directly within the bundle widget, improving the shopping experience.
To further personalize how these options appear, click on Edit swatches. Here, you can customize the swatch layout, labels, and appearance—for example:
Widget Preview
On the right side of the screen, you’ll see a live preview of the bundle widget. This preview updates in real-time as you configure your Product Add-on settings.
The widget preview shows exactly how the offer will appear on your product page, including the selected add-on product, pricing details, and any customizations you've made (like text or discount settings). This helps you visualize the final design and ensures everything looks correct before publishing.
Use this area to double-check your layout, confirm product selection, and make any adjustments to improve the customer experience.
3. Discount
In this section, you’ll decide how you want to price the add-on product. There are three discount types available:

Advanced Settings - The Advanced section gives you greater control over when, where, and to whom the bundle widget is shown. These settings are useful for precise targeting and scheduling. Let’s dive into each option:
1. Widget Position
By default, the widget will appear below the Add to Cart button.
To change its position, open the Shopify Theme Editor, and simply drag the app block to your preferred location on the product page—no coding required.
Embed Bundle via HTML
You can also embed this bundle manually on any page using HTML.
Display the bundle wherever you like by placing the provided HTML tag directly into your theme file.
Hide Shopify Elements

Simply enter the CSS selectors of the elements you'd like to hide.
For example:
.product__price
.product-form__buttons
This helps create a cleaner, more focused layout around your bundle widget.
