Fether Vs Frequently Bought Together CBB: Which Wins?

Increasing average order value (AOV) does not always require attracting more visitors or spending more money on advertising. Sometimes, the best opportunity comes from helping existing shoppers discover products that complement their original purchases.

The importance of a smooth shopping experience is clearer when we consider cart abandonment. According to the Baymard Institute's research, the global average cart abandonment rate reached 70.19% in its February 2025 update. Although product recommendation apps cannot solve every reason behind abandoned carts, relevant suggestions and convenient purchasing options can help merchants improve the shopping experience.

Personalization also plays an important role in ecommerce growth. McKinsey's 2021 research, The Value of Getting Personalization Right—or Wrong—is Multiplying, found that personalization typically drives a 10–15% revenue lift, with company-specific results ranging from 5% to 25%. These findings highlight the potential value of relevant customer experiences, although they do not represent guaranteed results from any particular Shopify app.

Two Shopify apps that support these strategies are Fether (Frequently Bought Together FT) and Frequently Bought Together CBB by Code Black Belt. Both apps provide product recommendations and bundle features that help merchants increase order value. Nevertheless, they approach upselling and cross-selling from slightly different perspectives.

In this comparison of Fether vs Frequently Bought Together CBB, we explore their features, advantages, limitations, and ideal use cases. The goal is to help Shopify merchants understand which app better supports their merchandising strategy, product catalog, and business priorities.

Introduction about Fether and Frequently Bought Together CBB

Fether is an all-in-one Shopify app that focuses on increasing AOV through AI-powered product recommendations, product bundles, and cross-selling opportunities. Its AI recommendation system analyzes order history and buyer behavior to suggest products that customers might purchase together.

Merchants can also create customized Mix & Match bundles, product add-ons, Buy Together offers, and related product sections.

Beyond traditional bundle recommendations, Fether offers quantity breaks, volume discounts, Buy One Get One (BOGO) promotions, Buy X Get Y deals, and free gifts. Its product page customization capabilities also help merchants create a more engaging shopping experience. This combination makes Fether particularly interesting for stores that want to manage several upselling and bundling strategies through one app.

Frequently Bought Together CBB, developed by Code Black Belt, takes a more focused approach to product recommendations and bundle promotions. The app combines AI-powered suggestions, manually configured bundles, and global recommendations to help shoppers discover complementary products. Its one-click add-to-cart functionality makes it easier for customers to purchase several recommended items without navigating between individual product pages.

The app also offers four bundle discount types: percentage discounts, fixed discounts, free items, and free shipping. Additionally, merchants can integrate product review platforms such as Judge.me, Loox, and Yotpo to display customer ratings alongside recommendations. Its customizable widget and flexible placement options support different Shopify themes and product page layouts.

Although both apps share the same goal of increasing AOV, their feature combinations create different opportunities for merchants. Fether emphasizes a broader product-bundling toolkit, while Frequently Bought Together CBB concentrates on recommendation flexibility and straightforward bundle purchasing.

Fether vs Frequently Bought Together CBB: What Are the Differences?

Both apps help Shopify merchants introduce complementary products at important moments in the shopping journey. However, their differences become clearer when we examine their recommendation systems, bundling capabilities, discounts, customization options, and pricing.

AI-powered product recommendations

AI recommendations represent an important feature in both apps because they help merchants identify products that complement customers' original selections.

Fether uses order history and buyer behavior to generate product suggestions and automatically build relevant upsell bundles. This approach can reduce the amount of manual work involved in selecting complementary products, especially for stores with extensive catalogs. Merchants can also combine AI recommendations with their own bundling strategies to maintain greater control over product combinations.

Frequently Bought Together CBB also provides AI-powered recommendations alongside manual and global recommendation options. This combination gives merchants flexibility when they want automated suggestions for some products and carefully selected combinations for others.

The main distinction lies in Fether's broader positioning around automatic bundle creation and related product merchandising. CBB places greater emphasis on combining recommendation methods within its bundle widget.

Personalization also has a wider business rationale. McKinsey's 2021 Next in Personalization research found that personalization typically drives a 10–15% revenue lift, although results vary across companies and industries. This statistic describes personalization across businesses rather than the guaranteed performance of either app. Nevertheless, it highlights the commercial value of relevant product suggestions.

Product bundling and cross-selling capabilities

Product bundling gives customers a convenient way to purchase complementary items together. It can also encourage shoppers to explore products that they might otherwise overlook.

Fether offers a dedicated product bundles builder that supports customized Mix & Match offers and upsell bundles. This capability suits merchants who want to create different product combinations instead of relying exclusively on automated recommendations. Its Buy Together offers, product add-ons, and related product sections further expand its cross-selling opportunities.

Frequently Bought Together CBB focuses on presenting complementary products in an accessible recommendation widget. Its one-click add-to-cart functionality creates a particularly convenient experience because shoppers can add suggested products without visiting multiple product pages. Merchants can combine AI recommendations with manual product pairings to create offers that reflect their merchandising priorities.

Therefore, Fether has a broader emphasis on building different bundle experiences, whereas CBB offers a streamlined approach to presenting and purchasing recommended product combinations.

Discounts and promotional flexibility

An attractive bundle becomes even more appealing when customers receive a meaningful incentive for purchasing additional products.

Fether supports several promotional strategies, including quantity breaks, volume discounts, BOGO offers, Buy X Get Y promotions, and free gifts. These options give merchants opportunities to encourage larger purchases, reward customers who buy multiple units, and promote specific product combinations.

Frequently Bought Together CBB offers four clearly defined bundle discount types: percentage discounts, fixed discounts, free items, and free shipping. Merchants can configure discounts globally or individually, depending on their promotional requirements.

Both apps support discounts that encourage customers to add more products to their orders. However, Fether provides a broader set of quantity-based promotional options, while CBB presents a straightforward selection of bundle-specific incentives.

Customization and shopping experience

A product recommendation widget should complement the store's design rather than interrupt the shopping experience. Its placement, appearance, and purchasing functionality can influence how naturally shoppers interact with additional offers.

Fether provides product page customization, mobile-friendly widgets, and page builder capabilities. These features support merchants who want to create a more customized storefront experience alongside their bundling campaigns.

Frequently Bought Together CBB offers a customizable widget that works with Shopify themes without requiring merchants to write code. Its flexible placement options allow merchants to position recommendations across different product page layouts. The app also integrates with popular review platforms, which adds customer ratings to product recommendations.

For merchants who prioritize broader product page customization, Fether offers an interesting advantage. Meanwhile, CBB provides a practical approach to widget customization and placement, with social proof as an additional strength.

Pros and Cons of Fether and Frequently Bought Together CBB

Both apps provide useful tools for increasing AOV, but their different feature combinations create advantages and limitations. Understanding these trade-offs helps merchants identify the app that matches their actual requirements rather than choosing solely based on the number of advertised features.

Fether's pros and cons

Fether offers a broad selection of merchandising tools that extend beyond traditional frequently bought together recommendations. Its advantages and limitations reflect its all-in-one approach.

Pros

  • Comprehensive bundling capabilities: Fether combines frequently bought together recommendations, Mix & Match bundles, product add-ons, and related products. This variety helps merchants develop different upselling and cross-selling strategies within one application.

Frequently Bought Together CBB's pros and cons

Frequently Bought Together CBB focuses on product recommendations and bundle purchasing through a customizable widget. Its strengths center on convenience, recommendation flexibility, and social proof.

Pros

  • Multiple recommendation methods: AI-powered, manual, and global recommendations give merchants flexibility when they manage product pairings across different collections or individual product pages.
  • Convenient one-click purchasing: Customers can add complementary products directly from the recommendation widget. This feature reduces unnecessary navigation and makes bundle purchasing more straightforward.
  • Four bundle discount options: Percentage discounts, fixed discounts, free items, and free shipping provide several ways to make product combinations more attractive.

  • Flexible widget placement: The no-code widget supports different Shopify themes and product page positions, which gives merchants control over how recommendations appear.
  • Published pricing tiers: Its Shopify listing provides a free plan and paid tiers based on monthly order volume, making the pricing structure easier to evaluate.

Cons

  • A narrower merchandising focus: Merchants who need an extensive collection of bundle-building and quantity-based promotional tools may find its core feature set less comprehensive than Fether's.
  • Limited dedicated quantity-break positioning: CBB offers several bundle discounts, but its published core feature description does not emphasize a dedicated quantity-break and volume-discount system comparable to Fether's.
  • Recommendation widgets remain central to its approach: Stores that want a broader product page-building toolkit may need additional applications to support their wider storefront customization strategy.
  • Order-volume limits affect plan selection: Its paid plans use monthly order thresholds. Growing merchants may need to move to a higher-priced plan as their order volume increases.

What Are Fether and Frequently Bought Together CBB Best For?

The best app depends on a store's merchandising strategy, product catalog, promotional requirements, and desired customer experience. Neither solution automatically suits every Shopify business.

A merchant with hundreds of products and several promotional campaigns may prioritize a different feature set from a smaller store that simply wants to recommend complementary items on product pages.

Fether is best for

Fether is a strong option for Shopify merchants who want a broader product-bundling and upselling toolkit.

Its AI-powered recommendations can support stores that need help identifying complementary products from their order history. Meanwhile, the Product Bundles Builder gives merchants greater flexibility when they want to create customized Mix & Match offers or develop product combinations for specific campaigns.

Fether also suits stores that frequently run volume discounts, quantity breaks, BOGO promotions, and free-gift campaigns. These features create opportunities for merchants to encourage larger purchases through different promotional approaches.

For example, a beauty store could recommend a cleanser and moisturizer together, create a skincare bundle with a customized discount, and introduce quantity breaks for customers purchasing multiple products. Fether's combination of recommendations, bundling, and promotional tools supports this type of merchandising strategy.

Overall, Fether makes a compelling choice for merchants who want one application to support several interconnected AOV growth strategies.

Frequently Bought Together CBB suits merchants who prioritize straightforward product recommendations and convenient bundle purchasing.

Its AI, manual, and global recommendation options give stores flexibility without requiring every product combination to follow the same strategy. Merchants can use automated suggestions for selected products while maintaining manual control over important product pairings.

The one-click add-to-cart feature also makes CBB particularly suitable for stores that want customers to purchase complementary products with minimal friction. Its discount options provide additional incentives, while integrations with Judge.me, Loox, and Yotpo introduce social proof into the recommendation experience.

For example, an electronics store could recommend a laptop sleeve and wireless mouse alongside a laptop. Customers could review the suggested products, see their ratings, and add the complementary items to their carts through the same widget.

CBB therefore represents a practical choice for merchants who value recommendation flexibility, a simple purchasing experience, and integrated customer reviews.
