MixMaxerThere are at least a dozen "best Shopify bundle apps" lists and every one of them is written by a vendor that puts itself first. We are a vendor too (MixMaxer is in the table). So instead of a ranking, this page gives you the columns that decide the choice and lets you sort: how the app charges, what it covers, whether it can test, and what merchants say about it. Everything below was read from each app's Shopify App Store listing on 1 November 2026; where a listing did not state something, the cell says so. Corrections to support@mixmaxer.com.
The column that matters most: how the app charges
Four pricing models exist in this category, and the model matters more than the sticker price because it decides what you pay when the offers work.
| Model | How the bill grows | Apps using it (listing wording) |
|---|---|---|
| Flat monthly price, no caps | It does not | Bundler ($0 / $9.99 / $19.99, "unlimited revenue & orders"), Bristm, formerly Rebolt ($19.99), MixMaxer ($0 / $9.99 / $19.99) |
| Capped by revenue the app attributes to itself | Every tier is "up to $N of additional revenue"; cross it and you move up | Fast Bundle ($19 up to $1,000 of monthly bundle sales, $49 up to $3,000, $139 up to $10,000), Kaching ($14.99 up to $1,000 additional revenue, $29.99 up to $5,000, $59.99 up to $10,000), Pumper (free up to $300, $9.99 up to $1,000, $29.99 up to $5,000, $49.99 unlimited), Rapi ($15 up to $1,000, $29 up to $10,000, $59 unlimited) |
| Capped by orders | Tiers by monthly order count | BOGOS (30 free orders lifetime, $29.99 for 300 a month plus $0.05 each beyond, $49.99 for 600, $109.99 for 2,000), Vitals ($29.99 up to 200 orders, $79 up to 1,000, $179 up to 5,000), Simple Bundles & Kits (free: 3 bundles and 50 orders a month; $24, $39, $149) |
| Tied to your Shopify plan or store revenue | Price depends on the plan you are on or your total revenue | Bundle Bear ($29.99 on Basic, $39.99 on Shopify, $49.99 on Advanced, $74.99 on Plus), Amplify, formerly PickyStory ("starts at $99.50 per month, volume based pricing, for brands generating up to $30k in total store revenue per month") |
Two things to notice. "Additional revenue generated by the app" is counted by the app, and it typically counts every order containing an offer, including orders you would have had anyway, so the cap arrives sooner than you expect. And "free to install" (Fast Bundle, Kaching, Rapi) is not the same as "free plan available" (Pumper, Bundler, BOGOS, Simple Bundles, Selleasy, MixMaxer); the first means the free tier is a trial-sized cap, the second means a plan you can stay on.

What "A/B testing" means differs widely between a feature named in a plan list and a real visitor split where checkout charges what each visitor saw; which bundle apps can actually A/B test an offer goes through that.
Pick by situation
You want free and simple fixed kits. Shopify Bundles. Accept the limits (no tiers, no mix & match, no upsells) and the 2.8-star experience some merchants report. What it can and cannot do.
You want everything in one app and a bill that never moves. Bundler (long-established, 17 languages, mix & match on the $9.99 tier) or MixMaxer (six offer types, A/B tests with automatic winner, profit per offer, Arabic admin; new, no reviews yet). Bristm is flat at $19.99 without a free plan.
You already use Vitals for reviews and pop-ups. Its bundle features are included; the order-capped price is for the whole suite.
You run gift-with-purchase campaigns above all. BOGOS has specialised in free gifts since 2014; check the order caps against your volume.
You want AI-picked cross-sells on every page. Selleasy, with a free tier limited by campaigns rather than orders.
You need inventory-accurate kits for fulfilment with SKU sync. Simple Bundles & Kits emphasises that; it is order-capped.
You are on a revenue-capped plan and the price just jumped. The flat-price options are the first row of the pricing table; how to switch without losing sales.
Four questions to ask any of them
- Is the discount a Shopify Function, so it applies in Shop Pay, express checkouts and POS without a script? Most listings say "works with Checkout"; ask about express buttons specifically. Why it matters.
- Is the widget a theme app extension, with nothing written into theme.liquid? How to measure what an app costs your page speed.
- What exactly is the cap on the plan you would be on, and what counts toward it?
- Can you measure the offer honestly: a visitor split, profit per variant, a holdout? Or only "revenue generated by the app"?
