What is Frequently Bought Together?
Frequently Bought Together (FBT) by Code Black Belt is one of the most popular Shopify recommendation apps. It uses an AI algorithm trained on billions of orders to display Amazon-style "frequently bought together" product groups on product pages. Merchants can also manually curate pairings and apply four discount types. The app holds a 4.9-star rating with 1,070+ reviews, offers a 30-day free trial, and costs $19.99/month flat rate with unlimited products, orders, and traffic. It supports Shopify Markets, multilingual stores, and includes basic widget customization. FBT is well-built for showing related product suggestions. But it is not a bundle builder.
Where Frequently Bought Together Falls Short
No guided kit builder
FBT displays a product widget below the main product. Customers see a list of suggested items and check boxes. There is no multi-step flow where they pick a main item, then accessories, then extras. That guided path is what turns 1-item carts into 4-5 item bundles.
No tiered reward stacking
FBT offers four discount types, but each bundle gets one discount. You cannot stack escalating tiers like "Buy 3 = 10% off. Buy 6 = 15% off + free shipping. Buy 9 = 20% off + free shipping + free gift." Progressive reward structures are what drive customers to add more.
No dollar-based thresholds
FBT triggers discounts based on product quantity only. It cannot set dollar thresholds like "spend $150 to unlock free shipping." That rules out luxury and B2B stores where order value matters more than item count.
One bundle architecture
FBT does one thing: show related products in a widget. It cannot build anchor product bundles, meal builders, subscription boxes, starter kit + refills combos, or gift set builders. If your catalog needs structured bundle flows, the widget falls short.
No sequential or free-flow navigation
Customers see the widget and either check items or skip. There is no sequential mode (finish step 1 before step 2 unlocks) or free-flow mode (browse categories in any order). Both modes are critical for complex bundles with 3+ categories.
Static widget placement
FBT sits below the product on the page. It competes for attention with reviews, descriptions, and other content. Customers who never scroll far enough never see it. A dedicated bundle experience puts the offer front and center.

Why Merchants Switch to Tiergain
AOV up 32% when customers build their own bundles
A skincare merchant switched from FBT's widget to Tiergain's guided kit builder. Customers went from checking a box on 1 suggested product to assembling 3-4 item routines with tiered discounts. AOV moved from $36 to $48 in the first 30 days.
Items per order jumped from 1.5 to 3.2
A pet food store used FBT to suggest treats alongside kibble. Most customers scrolled past the widget. With Tiergain's "build your box" flow - pick a food, then treats, then a toy - items per order more than doubled. The guided flow does what a static widget cannot.
Bundle revenue up 3x with stacked reward tiers
A supplements brand ran FBT with a flat 10% bundle discount. Revenue from bundles sat at $4,100/month. They moved to Tiergain and built progressive tiers: buy 3 = 10% off, buy 5 = 15% off + free shipping, buy 7 = 20% off + free gift. Bundle revenue hit $12,600/month within 6 weeks.
Frequently Asked Questions
Can I migrate my Frequently Bought Together bundles to Tiergain?
FBT and Tiergain work differently. FBT stores product pairings and AI recommendations. Tiergain builds structured bundle architectures. You set up your bundles fresh in Tiergain - most merchants go live with their first bundle in 15 minutes. You can also run both apps side by side if you want AI suggestions and full bundle building.
Is Tiergain cheaper than Frequently Bought Together?
FBT costs $19.99/month flat rate with unlimited products and orders. Tiergain pricing starts free, then $15 / $50 / $150 per month. FBT is a recommendation widget. Tiergain is a full bundle builder with 10 architectures, 3 reward types, and dollar thresholds. The ROI difference is in what each app does to your AOV, not the monthly fee.
How long does it take to set up Tiergain?
Most merchants go live with their first bundle in 15 minutes. Install the app, pick a bundle architecture, select your products, set reward tiers, and publish. No code, no developer, no theme editing required.
Does Frequently Bought Together have better AI than Tiergain?
Yes. FBT has a strong AI algorithm trained on billions of orders. It automatically suggests product pairings based on purchase patterns. Tiergain uses merchant-curated product selection instead. You choose exactly which products appear in each bundle step. FBT wins on autopilot convenience. Tiergain wins on bundle structure and reward flexibility.
Can I run Frequently Bought Together and Tiergain together?
Yes. They do not conflict. FBT handles passive product recommendations on product pages. Tiergain handles the active bundle-building experience. Many merchants run both - FBT for "you might also like" suggestions, Tiergain for structured bundles that stack discounts, free shipping, and free gifts.
Does Tiergain support product recommendations like FBT?
Tiergain is not a recommendation engine. It is a bundle builder. You define which products go into each bundle step and what rewards customers earn at each tier. If you need automatic "frequently bought together" suggestions, FBT does that well. If you need customers building their own multi-step bundles with escalating rewards, that is Tiergain.
Does Tiergain work with my Shopify theme?
Yes. Tiergain uses Shopify Theme App Extensions. It works with every Shopify theme, including Online Store 2.0 and custom builds. Drag and drop the bundle block into your theme. No code editing, no Liquid file changes. Removing the app leaves zero code behind.
