1. OC: Volume Discount Bundle App
This is our app, so read this section with that in mind. It launched in August 2023, carries the Built for Shopify badge, and has a 5.0 rating. That is far fewer reviews than the other apps in this list, so it has less public proof at scale.
What it does well: bundles and volume discounts by product or collection, BOGO and buy-X-get-Y inside quantity breaks, free gifts, post-purchase and thank-you-page upsells, and A/B testing on the paid plan. Reviewers mostly praise the volume discounts and quick support.
Where others are stronger: Easy Bundles has a more developed build-your-own-box flow, and Kaching and BOGOS have far more reviews from large stores.
Price: free for 1 campaign; Plus is $7.99 a month for unlimited campaigns, with a 7-day trial.
Best for: small and mid-size stores that want volume discounts plus simple bundles without a revenue-based bill.
2. Kaching Bundles App & Upsells
Kaching is the review leader in this category, with 5.0 rating. It launched in August 2022 and focuses on the classic quantity-break block: “1 item, 2 items (save 10%), 3 items (save 15%)” right above the add-to-cart button.
What it does well: you choose which products or collections get the offer, set the discount as a percentage, a fixed amount or a set price, and style the block to match your theme. A dashboard shows the extra revenue the offers bring in.
Price: free to install (free on development stores), then Starter at $14.99, Scale at $29.99 and Pro at $59.99 a month, each with a 7-day trial.
Best for: single-product and hero-product stores that want proven quantity breaks and are fine paying a monthly fee once live.
3. BOGOS: Free Gift Bundle Upsell
BOGOS has been on the App Store since 2014 and holds a 5.0 rating. It is the most complete promo tool here: automatic free gifts, BOGO and buy-X-get-Y, build-a-box and mix-and-match bundles, volume and tiered discounts, and checkout upsells.
What reviewers complain about: in recent 1–2 star reviews, one merchant said a fix broke multi-currency and bundles would not add to cart until a page reload. Another said a BOGO offer created many duplicate products in the store. A third said a cloned offer stayed live after uninstalling, and shoppers used it. Some also mention charges after removal and that simple style changes needed developer help.
Price: free for 30 orders (lifetime), then Basic $29.99, Grow $49.99 and Plus $109.99 a month, based on monthly order volume.
Best for: stores that run many promo types at once and have time to test each offer before launch.
4. Pumper Bundles Quantity Breaks
Pumper launched in May 2023 and already has 4.9. It is a close match to Kaching: quantity breaks and bundle offers for chosen products, with free gifts and BOGO deals placed inside the tiers.
What it does well: unit, percentage or flat-amount discounts, gifts inside tiers, and a revenue tracker. Its pricing is tied to the extra revenue the app creates, which keeps costs low for small stores.
Price: free up to $300 in revenue, then $9.99 (up to $1,000), $29.99 (up to $5,000) and $49.99 (unlimited) a month.
Best for: new stores testing quantity breaks that want a free start and a cheap first paid tier.

5. Easy Bundles: Bundle Builder
Easy Bundles by Skai Lama has 4.9 and launched in September 2022. Its strength is the guided builder: shoppers pick items step by step to build their own bundle or fill a box, and tiered discounts, quantity breaks, buy-X-get-Y and free gifts can apply.
What reviewers complain about: low-star reviews from 2025–2026 mention slow support replies, charges after uninstalling, and the app slowing down or crashing when a store created thousands of bundles. Others say the widget cannot be placed exactly where they want and that products with many sizes are hard to handle.
Price: free up to $500 in bundle sales a month, then Essential $29, Growth $49 and Scale $99 a month, each capped by bundle sales.
Best for: gift, beauty and food stores where “build your own box” is the main offer.
How to choose the best bundle app for your Shopify store
- Match the offer type. Quantity breaks, free gifts and build-a-box are different tools. Pick the app built for your main offer, not the one with the longest feature list.
- Check how the price grows. Kaching and our app charge a flat fee. Pumper and Easy Bundles charge by revenue or bundle sales. BOGOS charges by orders. Model your next 6 months, not today.
- Test with your theme and currencies. Several complaints above are about multi-currency, variants and widget placement. Run a test order in each market before launch.
- Plan the exit. Reviews mention offers left live and charges after uninstalling. Turn off every campaign before you remove any app, then check your Discounts page.
- Look at support, not just stars. Read the newest 1–2 star reviews. Every app here rates 4.9+, so recent support stories tell you more.
