How to choose a Shopify bundle app: a 12-point checklist (with scores)

Most bundle apps look the same in screenshots. A checklist makes the differences visible: what's free, how the bill grows, where the offer shows and who helps you set it up. Here are 12 points, and how six popular apps score.

All guides · Updated 2026-10-22

We make ZS Bundles, so weigh that. The facts about other apps are from their Shopify App Store listings, checked on 22 October 2026. Apps change their plans, so check the listing before you install.

The 12 points

A free plan that works on a live store, not only a development store.
Every bundle type on that free plan, so you can test any offer before paying.
Quantity breaks.
Buy X get Y / BOGO.
Mix & match or build-a-box.
Free gifts.
A first paid plan under $15 a month.
Price not based on revenue, so a good month doesn't move your tier.
A free trial of 14 days or more.
Offer on the product page, styled to your store.
An established track record: 1,000+ reviews on the App Store.
Help with set-up listed on the plan you'd use.

How six apps score

Scored from each app's Shopify App Store listing (description, feature list and plans), checked 22 October 2026. A point is given only when the listing shows it; "–" means the listing doesn't show it, not that the app can't do it.

Read the score honestly

We wrote the checklist, and we make one of the apps, so the points match what we care about. Change the weights for your store:

If track record matters most, point 11 outweighs the rest, and every other app here beats us. That's a fair reason to choose them.
If you only run quantity breaks, Bundler's free plan may be all you need.
If you need a multi-step builder page, Easy Bundles lists one and we don't.
If you want every bundle type free to test, a low bill that doesn't follow your revenue, and set-up done for you, ZS Bundles scores highest.

Three checks no listing can answer

Install it and look at your own product page on a phone. Does it match your theme?
Test the cart. Add the bundle, change a quantity, remove an item. The price should follow every change.
Read the newest 1–3 star reviews, not just the average, to see how problems get handled.
