Shopify Bundle Apps Compared: Bundler vs Frequently Bought Together vs Bold Bundles
Product bundling is one of the highest-ROI tactics in ecommerce — but many Shopify merchants pay for a bundle app that duplicates features they already have in their upsell app, or pay for a paid tier they don't need when the free tier does the job.
Bundle Apps vs Upsell Apps: The Overlap
Before installing a dedicated bundle app, check what your existing upsell app already does. ReConvert, Honeycomb, and Aftersell all include some form of product bundling or "frequently bought together" recommendations. Merchants often install a standalone bundle app without realising their upsell tool covers the same use case — or install both and run competing bundle offers on the same product pages.
The key distinction: upsell apps focus on post-purchase and cart-stage offers (add another item to the order). Bundle apps focus on pre-purchase presentation (show products sold together at a discount on the product page, before the cart). If you need both, run separate tools. If you only need one, identify which stage matters most for your store before paying for both.

Prices as of May 2026. Bundler and Frequently Bought Together are the most popular by install count. Bold Bundles has no free tier — the highest entry cost in category.
Bundler
Bundler is the most flexible bundle app in terms of bundle types. It supports mix & match bundles (buy any 3 from a collection at X% off), fixed product bundles (these specific 3 items together at $Y), step bundles (buy 2 get 10% off, buy 4 get 20% off), and gift-with-purchase bundles. This variety makes it suitable for stores with complex merchandising needs.
The free tier supports basic fixed bundles — sufficient for most early-stage stores. The Premium tier ($8.99/mo) unlocks mix & match, which is where Bundler's real differentiation lies. At $8.99/mo it's the cheapest paid bundle app in the category, making it the best-value option for most stores.
Best for
- • Mix & match bundle promotions
- • Budget-conscious stores ($8.99/mo)
- • Stores with many SKU variants to bundle
- • Step/tiered discount bundles
Not ideal for
- • AI-driven recommendations (manual only)
- • Stores wanting Amazon-style "customers also bought"
- • Post-purchase bundle offers
Frequently Bought Together
Frequently Bought Together (by Code Black Belt) replicates the Amazon "customers who bought this also bought" experience on Shopify product pages. Its core feature is an AI recommendation engine that analyses your store's order history to automatically suggest which products to pair together — no manual configuration required. For stores with meaningful order history (1,000+ orders), the AI recommendations are generally strong and outperform manually curated bundles.
The free tier works for one product, which makes it useful for testing the concept on your best-selling product before committing to the $19.99/mo paid tier. The paid tier ($19.99/mo, unlimited products) is the most straightforward pricing in category — no tiers to navigate, no usage-based costs.
The limitation: it only does one thing. If you want mix & match bundles, step discounts, or gift-with-purchase, you need Bundler or Bold. FBT is the right tool when the "customers also bought" widget is specifically what you need.
Bold Bundles
Bold Bundles is the original bundle app in the Shopify ecosystem and still has strong brand recognition, but it's the most expensive option with no free tier. At $19.99/mo entry (Basic), you're paying more than Bundler Premium ($8.99/mo) for a less flexible feature set. The Advanced tier ($49.99/mo) is appropriate for stores running complex fixed-bundle merchandising at high volume, but for most use cases, Bundler offers comparable or better functionality at a lower price.
Common overspend pattern: merchants who installed Bold Bundles in 2020–2022 when it was the only credible option and haven't re-evaluated since the category became more competitive. If you're on Bold Bundles, it's worth checking whether Bundler at $8.99/mo would cover your actual use case.
