Frequently Bought Together review

Frequently Bought Together builds product-page bundle and cross-sell widgets for Shopify stores: it looks at what a shopper is viewing, suggests items people tend to buy alongside it, and handles the bundled discount and checkout mechanics when they add everything to cart in one click. The developer listed on the Shopify App Store is Code Black Belt, but the app is powered by Shop Circle, a Shopify-app portfolio company that recently raised $100M to keep acquiring apps like this one, worth knowing before you install it as though it were an independent indie studio. Pricing runs free forever on the Starter plan, then $9.99 to $39.99 a month by order volume, per the live Shopify App Store listing checked twice on October 23, 2026. It carries a 4.9 out of 5 rating from 1,212 reviews on the App Store, the largest review base of any Shopify upsell app in this category, and it’s Built for Shopify certified.

Where it shines

The review count alone sets Frequently Bought Together apart: 1,212 ratings at a tied-highest 4.9 out of 5, more than double Zipify OneClickUpsell’s 569 and well ahead of Candy Rack’s 265. The Starter plan backs that up with a genuine free tier, up to 3 manual bundles, basic customization, and basic support, no credit card and no trial clock running. Four configuration modes cover most use cases without custom work: Automatic pulls AI-driven recommendations from a store’s own purchase history, Manual lets a merchant hand-pick the bundle, Random pulls from a filtered collection, vendor, tag, or type, and Global applies a single bundle store-wide. Discount types cover percentage off, a fixed amount off, the cheapest item free, or free shipping, and analytics tracks clicks, conversions, and sales, with a Meta Pixel integration for anyone running paid social on top of it. For a store that just wants “customers also bought” widgets on product pages without touching the cart or checkout experience, this is the most proven option of the three apps in this category.

Where it frays

The setup process for manual bundles is the single most repeated complaint in the App Store’s low-rated reviews: DJS&K Handcrafted called the builder “not user friendly,” Backwards Boutique rated it 1 star over how “confusing and not easy to navigate” it is, and several other reviewers echoed the same frustration independently. A second, separate complaint thread describes the app simply breaking: Brown Living reported it had been non-functional for 4 months, and Elixir Health & Wellbeing gave it 2 stars after it stopped working and reportedly coincided with a spike in bot traffic on their store, an unusual pairing no other reviewer corroborated. Indulgeo Essentials added a third kind of complaint entirely, rating the support team 1 star as “stubborn” and unwilling to act on feedback. None of these reviews represent the typical experience on a 4.9-star app, but they cluster tightly enough around setup and reliability to be worth reading before assuming a bundle will work on the first try. The app also has no native A/B testing, and the only placement it covers is the product page, so a store that wants to test offers at the cart or checkout needs a second tool.

Pricing reality

Every paid tier gets the identical feature list, so the price climbs with monthly order count only, never because a feature got locked behind a higher plan. That’s the Shopify App Store’s own pricing table, confirmed on two independent fetches on October 23, 2026, the page a merchant actually installs from. Code Black Belt’s product page shows a different, unexplained number instead: a single headline reading “Start from $19.99/month,” with no tier breakdown behind it. That’s almost exactly double the App Store’s $9.99 entry price, and nothing on either page accounts for the gap; it could be a stale marketing page, a region-specific toggle, or something else entirely. Until Code Black Belt clears that up, the App Store’s $9.99 figure is the one to budget around, since it’s the number that actually governs a new install.

Who should buy it, and who should skip it

Buy Frequently Bought Together if the goal is “customers also bought” bundles on product pages, and a free tier matters while testing whether bundling moves average order value at all. Its review base is the deepest of the three apps here, and the Professional tiers stay cheap well into a store doing a few hundred orders a month. Skip it if upsells need to show up in the cart drawer, at checkout, or on the post-purchase page: Candy Rack covers all of those placements in one app for a flat per-order fee, and Zipify OneClickUpsell adds a true one-click post-purchase recharge that Frequently Bought Together doesn’t attempt. Anyone weighing all three side by side should start with our best Shopify upsell and cross-sell apps guide, and a store already running on-site popups should pair whichever upsell app it picks with a tool from our best popup and CRO tools for ecommerce guide, since popups and upsells solve different problems at different moments in the same checkout.
