Why Product Bundles Are One of the Fastest Ways to Grow Revenue
Most Shopify stores spend their time chasing new traffic. The smarter play? Getting more value from the customers already on your site. Product bundles do exactly that - they give shoppers a reason to add more items to their cart while feeling like they’re getting a deal.
The math is straightforward. If your average order value is $45 and you increase it by even 20% through bundle offers, that’s $9 more per order. On 1,000 monthly orders, that’s $9,000 in extra revenue without spending a dollar on ads.
We tested over 20 bundle apps on Shopify to find the 10 that actually deliver. Every app on this list is Built for Shopify certified and handles at least three bundle types - from simple product bundles and volume discounts to mix-and-match builders and BOGO deals.
How we chose these apps: Each app was tested on live stores and evaluated on bundle flexibility, ease of setup, pricing fairness, performance impact, and merchant reviews. We focused on apps that increase AOV without complicating the shopping experience.
Best Overall Bundle App
1. Kaching Bundles & Upsells - Best overall bundle app
Kaching is the most popular bundle app on Shopify right now, and after testing it we understand why. It handles fixed bundles, mix-and-match offers, quantity breaks, and BOGO deals from a single dashboard. The setup takes minutes and the bundle widgets look native to your theme.
Why we recommend it: The A/B testing feature sets Kaching apart. You can test different discount structures, bundle layouts, and product combinations to find what converts best. The analytics dashboard shows exactly how much revenue each bundle generates, so you can double down on what works. Multilingual support and multi-currency pricing make it a solid choice for international stores.
What to watch out for: Pricing is based on how much additional revenue the app generates. The $14.99 Starter plan caps at $1,000 in bundle revenue per month. If your bundles are driving serious volume, you’ll move to the $29.99 or $59.99 tier fairly quickly.
| Rating | 5/5 (3,505 reviews) Built for Shopify |
| Pricing | Free (dev stores), Starter $14.99/mo, Scale $29.99/mo, Pro $59.99/mo |
| Best For | Stores that want one app to handle all bundle types with built-in A/B testing |
| Key Features | Fixed bundles, mix-and-match, quantity breaks, BOGO, A/B testing, analytics dashboard |
Best for BOGO & Free Gifts
2. BOGOS: Free Gift Bundle Upsell - Best for BOGO campaigns
BOGOS is the go-to app if your primary strategy is “buy X, get Y” promotions. It powers free gift campaigns, tiered gifting, and BOGO deals for over 79,000 Shopify stores. The auto-add-to-cart feature is especially smooth - customers see the gift appear without needing to click anything.
Why we recommend it: The targeting rules are where BOGOS really shines. You can set gift offers based on cart value, specific products, customer tags, geographic location, and even purchase history. The real-time analytics show how each promotion impacts conversion rates and AOV, so you can fine-tune offers quickly. POS and headless commerce support is a nice bonus for stores selling across multiple channels.
What to watch out for: The free plan is limited to 30 lifetime orders - it’s really just a trial. The Basic plan at $29.99/mo only covers 300 monthly orders through BOGOS, and Shopify Basic stores are locked to this tier. Higher-volume stores on Shopify Professional or Plus plans will need the $49.99 or $109.99 tiers.
| Rating | 5/5 (3,345 reviews) Built for Shopify |
| Pricing | Free (30 lifetime orders), Basic $29.99/mo, Professional $49.99/mo, Plus $109.99/mo |
| Best For | Stores running frequent BOGO promotions and free gift campaigns |
| Key Features | BOGO offers, free gift with purchase, auto-add-to-cart, advanced targeting, POS support, analytics |
Best for Volume Discounts
3. Pumper Bundles Quantity Breaks - Best for volume discounts
Pumper specializes in quantity breaks and tiered pricing - the “buy more, save more” approach that works particularly well for consumable products and items customers stock up on. The bundle widgets are fully customizable and integrate cleanly with most Shopify themes.
Why we recommend it: The free plan is genuinely useful, covering up to $300 in extra revenue per month. The discount structure is flexible - you can offer flat discounts, percentage-based deals, or fixed prices per unit at different quantity tiers. We found the setup process among the fastest of any bundle app we tested. Within 10 minutes, we had volume discounts live on product pages with tier tables showing customers exactly how much they’d save.
What to watch out for: The revenue caps on each plan are the main limitation. If your bundles are generating more than $1,000/mo in extra revenue, you’ll need the Growth plan at $29.99/mo. The Unlimited plan at $49.99/mo removes caps entirely.
| Rating | 5/5 (2,580 reviews) Built for Shopify |
| Pricing | Free (up to $300 revenue), Starter $9.99/mo, Growth $29.99/mo, Unlimited $49.99/mo |
| Best For | Stores selling consumables or products customers buy in multiples |
| Key Features | Quantity breaks, tiered pricing, volume discounts, free gifts, BOGO, fully customizable widgets |
Best for Mix-and-Match Bundles
4. FBP | Fast Bundle Product - Best for mix-and-match
Fast Bundle supports eight different bundle types, but its mix-and-match functionality is where it really stands out. Customers choose from a curated selection of products to build their own bundle at a discounted price - think meal kits, skincare routines, or gift boxes.
Why we recommend it: The variety of bundle types means you’re not locked into a single strategy. You can run fixed bundles on some products, volume discounts on others, and a mix-and-match builder for curated collections - all from the same app. The AI-powered “Frequently Bought Together” feature automatically suggests products based on real purchase data. We also liked the bundle analytics that break down performance by bundle type.
What to watch out for: The free plan is for development stores only. Live stores start at $19/mo (capped at $1,000 in monthly bundle sales), which jumps to $49/mo at $3,000 and $139/mo at $10,000. Higher-volume stores should factor this into their ROI calculations.
| Rating | 5/5 (2,209 reviews) Built for Shopify |
| Pricing | Free (dev stores), Standard $19/mo, $49/mo, $139/mo (based on bundle sales volume) |
| Best For | Stores with complementary products that lend themselves to mix-and-match collections |
| Key Features | 8 bundle types, mix-and-match builder, AI frequently bought together, volume discounts, BOGO, analytics |
Best All-in-One App with Bundling
5. Vitals - Best all-in-one with bundling
Vitals takes a different approach than dedicated bundle apps. It packs 40+ tools into a single app - product reviews, wishlists, currency converter, sticky cart, urgency timers, and yes, product bundles. If you’re running five or six separate apps and want to consolidate, Vitals can replace most of them.
Why we recommend it: The bundle feature alone wouldn’t make this list - it’s the combination of bundles with complementary tools that makes Vitals compelling. You can create unlimited product bundles, add volume discounts, and pair them with social proof (reviews), urgency (countdown timers), and trust (trust badges) - all from one app. That means one subscription, one set of settings, and one app impacting your page speed instead of six.
What to watch out for: Vitals doesn’t have a free plan - it’s $29.99/mo flat. The bundling features are solid but not as deep as dedicated apps like Kaching or Fast Bundle. If bundling is your primary focus, a specialized app gives you more control. Vitals works best when you need bundles plus several other tools.
| Rating | 4.9/5 (2,624 reviews) Built for Shopify |
| Pricing | $29.99/mo (all features included), free for development stores |
| Best For | Stores wanting to consolidate multiple apps into one (bundles + reviews + 40 other tools) |
| Key Features | Unlimited bundles, volume discounts, product reviews, wishlists, currency converter, 40+ marketing tools |
Best for Upselling with Bundles
6. Selleasy - Best for upselling with bundles
Selleasy approaches bundles from the upsell angle. Instead of creating standalone bundle products, it displays “Frequently Bought Together” suggestions and product add-ons at multiple touchpoints - the product page, cart drawer, post-purchase page, and thank you page.
Why we recommend it: The multi-touchpoint approach is what makes Selleasy effective. A customer might skip the product page suggestion but add a complementary item from the cart drawer offer. Post-purchase upsells with one-click add are particularly powerful since the customer has already committed to buying. The Amazon-style “Frequently Bought Together” widget is clean and converts well. We saw a 12-15% take rate on well-matched product suggestions during our testing.
What to watch out for: Selleasy is better at cross-selling related products than creating traditional bundles with shared discounts. If you need custom bundle builders, mix-and-match experiences, or complex discount tiers, a dedicated bundle app is a better fit. Selleasy works best alongside a traditional bundle app rather than replacing one.
| Rating | 4.9/5 (2,163 reviews) Built for Shopify |
| Pricing | Free (up to 50 orders/mo), $9/mo, $19/mo, $29/mo (based on order volume) |
| Best For | Stores focused on cross-selling related products at multiple touchpoints |
| Key Features | Frequently bought together, product add-ons, cart upsells, post-purchase upsells, multi-currency support |
Best Free Bundle App
7. Bundler - Best free bundle app
Bundler has been around longer than most bundle apps on Shopify, and its free plan is the most generous in the category. You get unlimited bundles, unlimited orders, and no revenue caps - features that competitors charge $20-50/mo for.
Why we recommend it: For stores testing bundling for the first time, Bundler removes all financial risk. The free tier includes classic bundles, volume discounts, and quantity breaks with no restrictions on how many you create or how much revenue they generate. The interface is straightforward - pick your products, set your discount, choose your display style, and you’re live. The paid Premium plan at $9.99/mo adds mix-and-match bundles, custom landing pages, and funnel upsells for when you’re ready to scale.
What to watch out for: The free plan doesn’t include mix-and-match bundles or bundle analytics. If you want data on which bundles convert best, you’ll need the Executive plan at $19.99/mo. The widget designs are functional but not as polished as newer apps like Kaching or Pumper.
| Rating | 4.9/5 (1,946 reviews) Built for Shopify |
| Pricing | Free (unlimited bundles & orders), Premium $9.99/mo, Executive $19.99/mo |
| Best For | Budget-conscious stores and merchants testing bundling strategies for the first time |
| Key Features | Unlimited free bundles, classic bundles, volume discounts, quantity breaks, custom landing pages (paid) |
Best for Beginners
8. Rapi Bundles Builder & Upsells - Best for beginners
Rapi Bundles is designed for merchants who want to get bundles running quickly without a learning curve. The setup wizard walks you through creating your first bundle in under five minutes, and the pre-built templates handle the design work for you.
Why we recommend it: The forever-free plan covers up to $100 in monthly bundle revenue, which is enough for new stores to validate the concept. Rapi includes guided tutorials within the app that explain not just how to create bundles, but which types work best for different product categories. The A/B testing feature - unusual at this price point - lets you compare discount structures to find what converts. AI-powered upsell suggestions take the guesswork out of product pairing.
What to watch out for: The $100/mo revenue cap on the free plan is low. Once your bundles gain traction, you’ll need the Starter plan at $15/mo (capped at $1,000/mo in bundle revenue). The app is newer than competitors like Bundler, so the feature set is still growing.
| Rating | 5/5 (922 reviews) Built for Shopify |
| Pricing | Forever Free (up to $100/mo revenue), Starter $15/mo (up to $1,000/mo) |
| Best For | New store owners creating their first bundle offers |
| Key Features | Guided setup wizard, A/B testing, AI upsell suggestions, bundles, volume discounts, BOGO deals |
Best for Inventory Sync & 3PL
9. Simple Bundles & Kits - Best for inventory sync and 3PL
Simple Bundles tackles the problem that most bundle apps ignore: what happens after the sale. When a customer buys a bundle, Simple Bundles breaks it down into individual SKUs for fulfillment, keeping your inventory accurate across all sales channels and third-party logistics providers.
Why we recommend it: If you use a 3PL or have complex inventory requirements, Simple Bundles is the best choice. It syncs bundle components with your actual inventory in real time - no overselling, no manual adjustments. The app supports multipacks, curated sets, subscription bundles, and mix-and-match options. B2B pricing support makes it one of the few bundle apps that works well for wholesale alongside DTC.
What to watch out for: The free plan limits you to three bundles. For most stores, the Starter plan at $24/mo is the realistic starting point. The interface prioritizes functionality over flashy design - the widgets are clean but not as visually striking as Kaching or Fast Bundle. This is an operational tool first, a marketing tool second.
| Rating | 4.9/5 (671 reviews) Built for Shopify |
| Pricing | Free (up to 3 bundles), Starter $24/mo, Advanced $49/mo, Plus $149/mo |
| Best For | Stores using 3PL fulfillment or managing complex multi-SKU inventory |
| Key Features | Real-time SKU inventory sync, 3PL integration, multipacks, subscription bundles, B2B pricing, mix-and-match |
Best for Build-a-Box
10. EB | Easy Bundle Builder - Best for build-a-box experiences
Easy Bundle Builder by Skai Lama focuses on multi-step bundle experiences - the “build your own box” format where customers walk through a guided process selecting products at each step. Think curated gift boxes, snack boxes, or custom product kits where the shopper picks from categories.
Why we recommend it: The step-by-step bundle builder is the most polished we’ve tested. You define the steps (choose a base, add toppings, pick a side), set minimum and maximum selections per step, and apply tiered discounts based on how many items they add. The design templates are modern and integrate well with Online Store 2.0 themes. Discounting rules are flexible - flat amounts, percentages, or dynamic pricing based on bundle size.
What to watch out for: Pricing is steep compared to other bundle apps. The free plan caps at $500/mo in bundle sales. The Essential plan is $49/mo (up to $5,000 in sales), and it jumps to $149/mo for Plus. If your store does high-volume bundle sales, the Enterprise plan at $399/mo covers up to $75,000 per month. This is a premium tool with pricing to match.
| Rating | 4.9/5 (789 reviews) Built for Shopify |
| Pricing | Free (up to $500/mo sales), Essential $49/mo, Plus $149/mo, Enterprise $399/mo |
| Best For | Stores offering curated gift boxes, custom kits, or step-by-step product selection |
| Key Features | Multi-step bundle builder, build-a-box, tiered discounts, design templates, OS 2.0 support |
How to Choose the Right Bundle App
Not every store needs the same type of bundling. Here’s how to match the right app to your situation:
Just starting out (under $10K/mo): Start with Bundler (free, unlimited bundles) or Rapi Bundles (free up to $100/mo with guided setup). Test a few simple product bundles and volume discounts to see what your customers respond to. Once you know what works, you can upgrade to a more feature-rich app.
Growing stores ($10K-$50K/mo): Move to Kaching or Pumper for more advanced features like A/B testing, detailed analytics, and better widget customization. If your products lend themselves to mix-and-match or build-a-box, Fast Bundle or Easy Bundle Builder are worth the investment.
High-volume stores ($50K+/mo): At this level, you want apps that can handle scale without breaking your workflow. Simple Bundles is the right choice if inventory accuracy and 3PL integration are critical. Kaching Pro or BOGOS Plus handle high order volumes with full analytics. Consider pairing a dedicated bundle app with Selleasy for post-purchase cross-sells.
Stores already using multiple apps: If you’re running separate apps for reviews, wishlists, and other features alongside bundles, Vitals can consolidate everything into one subscription. The bundling features are good enough for most stores, and you’ll save on your total app spend.

Frequently Asked Questions
Do bundle apps slow down my Shopify store?
The apps on this list are all Built for Shopify certified, which means they meet Shopify's performance standards. That said, any app adds some weight to your storefront. We tested page load times with each app installed and found minimal impact - typically under 100ms of additional load time. The key is choosing one bundle app and sticking with it rather than stacking multiple bundling tools that overlap in functionality.
What type of bundle works best for increasing average order value?
Volume discounts and quantity breaks tend to deliver the most consistent AOV lifts because they encourage customers to buy more of what they already want. Mix-and-match bundles work well for stores with complementary products, like skincare routines or meal kits. BOGO offers drive the highest conversion rates but at lower margins. The best approach depends on your product catalog and margins - most stores see the biggest gains from testing two or three bundle types and doubling down on what converts.
Can I use a bundle app with my existing upsell or cross-sell app?
Yes, but be careful about overlap. A dedicated bundle app like Kaching or Pumper handles product page bundles and quantity breaks, while an upsell app like ReConvert focuses on post-purchase offers. These complement each other well. Problems arise when two apps try to display widgets in the same location - like two different 'frequently bought together' sections on the same product page. Pick one app per touchpoint and you'll avoid conflicts.
Are free bundle apps good enough for a growing store?
Several apps on this list offer genuinely useful free plans. Bundler gives you unlimited bundles on its free tier, Rapi Bundles covers up to $100 in monthly bundle revenue for free, and Pumper includes a free plan for up to $300 in extra revenue. For stores under $10K per month, these free tiers are more than enough to test bundling strategies and see real results before committing to a paid plan.
