Frequently Bought Together: Boost Cross-Selling with Smart Cart Bundles

Frequently Bought Together (FBT) is a powerful cross-selling feature that displays relevant product bundle suggestions directly in the cart. By recommending complementary items at the right moment, FBT encourages customers to add more products to their order—effortlessly increasing average order value (AOV) without interrupting the checkout flow.

This article explains what Frequently Bought Together is, how it works in the cart, why it’s effective, and how to set it up.

✅ Note: The setup process is the same as creating Product Bundles on the Product Page, as described in the linked guide. The only difference is the display location (Cart).

What Is Frequently Bought Together?

Frequently Bought Together shows a curated group of products that are commonly purchased together and allows customers to add them to their cart with one click.

For example:

• Phone → Phone case + Screen protector

• Skincare product → Cleanser + Moisturizer

• Coffee machine → Coffee pods + Filters

Instead of relying on customers to search for related items, FBT proactively presents them at the cart stage, where purchase intent is already high.

How Frequently Bought Together Works in the Cart

1. A customer adds a product to their cart.

2. The cart displays a Frequently Bought Together bundle related to that product.

3. Customers can:

   • Select or deselect recommended items

   • Add the entire bundle to the cart instantly

4. Any associated bundle discount is automatically applied at checkout.

This seamless experience removes friction and makes upselling feel helpful rather than pushy.

Key Features of Frequently Bought Together

• Cart-Based Display – Appears in the cart or cart drawer for maximum impact

• Custom Product Bundles – Manually choose which products are grouped together

• Optional Discounts – Percentage or fixed discounts for bundled items

• One-Click Add to Cart – Easy selection without leaving the cart

• Smart Cross-Selling – Encourages relevant add-ons instead of random products

Why Use Frequently Bought Together?

1. Increase Average Order Value (AOV)

Customers are more likely to add extra items when they’re already committed to buying.

2. Improve Customer Experience

Shoppers appreciate reminders for useful add-ons they may have forgotten.

3. Higher Conversion Than Product Page Upsells

Cart-level recommendations reach customers at a high-intent moment.

4. Faster Decision-Making

Pre-selected bundles reduce thinking time and simplify purchasing.

5. Boost Product Discovery

Helps less-visible or accessory products gain more exposure.

Setup Process (Same as Product Bundles on Product Page)

The setup process for Frequently Bought Together is the same as creating Product Bundles, including:

• Selecting the main product

• Choosing bundled products

• Configuring discounts (optional)

• Customizing bundle text and labels

The only difference is that the bundle is displayed in the Cart, not on the Product Page.

You can follow the same step-by-step workflow outlined in the Product Bundles guide and simply choose the Cart as the placement.

Best Practices for Frequently Bought Together

✔ Choose Complementary Products
Focus on items that genuinely add value when used together.

✔ Limit Bundle Size
2–4 products per bundle works best to avoid overwhelming customers.

✔ Use Clear, Benefit-Driven Copy
Example: “Complete your setup” or “Customers usually add these.”

✔ Offer a Small Incentive
Even a modest discount can significantly improve bundle acceptance.

✔ Test & Optimize
Try different product combinations to see what converts best.

Conclusion

Frequently Bought Together is a simple yet highly effective way to maximize revenue per order by leveraging customer buying behavior. By showing smart bundle suggestions in the cart, you meet customers at the perfect moment—when they’re already ready to buy.

Since the setup process mirrors Product Bundles on the Product Page, it’s quick to implement and easy to scale across your store.
