MixMaxer"Free plan available" on the Shopify App Store covers everything from a plan you can run a store on to a 30-order trial that never resets. For a new or small store choosing a bundle app, the question is not whether there is a free tier but what ends it. This page reads the fine print of nine apps from their App Store listings on 1 November 2026. We make one of them, so MixMaxer is in the table with the same columns as the others.
"Free plan" versus "free to install"
The App Store uses two labels. Free plan available means a tier you can stay on. Free to install means the app can be installed at no charge, but the usable tiers are paid; Fast Bundle, Kaching and Rapi carry that label, with paid tiers from $19, $14.99 and $15 respectively (Rapi's listing also mentions a "forever free" tier capped at about $100 a month of attributed revenue). Shopify's own Bundles app is simply free.
The free tiers, side by side
| App | Free tier | What ends it | What the free tier lacks |
|---|---|---|---|
| Shopify Bundles (Shopify) | The whole app is free | Nothing | Volume tiers, mix & match, cart upsells, analytics beyond orders; rated 2.8 (571 reviews) |
| Bundler | Free "for everyone", unlimited revenue and orders | Nothing on volume; features | Mix & match and some combinations are on the $9.99 tier, analytics on $19.99 |
| Selleasy (Logbase) | Free, unlimited orders, up to 5 campaigns | A sixth campaign | Higher AI-recommendation counts on paid tiers ($9, $29, $59) |
| Pumper | Free up to $300 of "extra revenue generated by Pumper" | $300 of attributed sales, then $9.99 (up to $1,000), $29.99, $49.99 | Reached in days by a working offer |
| Rapi (Rapid Bundles) | "Forever free" up to about $100 a month of attributed revenue | $100 of attributed sales a month, then $15, $29, $59 | Same |
| BOGOS | 30 free orders, lifetime | The 31st order ever, then $29.99 for 300 orders a month | A trial in practice |
| Simple Bundles & Kits | 3 bundles and 50 orders a month | The 4th bundle or 51st order, then $24 ($14 under 100 orders), $39, $149 | Scale |
| Vitals | Free for development stores only | Going live, then $29.99 for up to 200 orders | Not a free plan for a live store |
| MixMaxer | 2 live offers, 1 running A/B test, all six offer types, cart upsell bar, profit per offer, unlimited orders and revenue | Needing a third live offer or a second simultaneous test, then $9.99 unlimited offers | Product card badges, countdown timers, order limits, customer targeting (Growth); holdout group, CSV, weekly email (Pro) |
Kaching and Fast Bundle: free to install, no stay-on free tier stated; first paid tiers $14.99 (up to $1,000 of additional revenue) and $19 (up to $1,000 of monthly bundle sales).
Which cap you can live with
- Caps on attributed revenue (Pumper, Rapi) end the moment the offer works, because the app counts every order that contains an offer. Treat them as trials.
- Caps on orders (BOGOS, Simple Bundles) end on volume regardless of whether the offer did anything.
- Caps on the number of offers or campaigns (Selleasy, MixMaxer) scale with how many things you run, not with sales. A single-product store can stay on them indefinitely.
- Feature-gated free tiers (Bundler) are free on volume forever; you pay when you need a specific offer type.
For a store under about a hundred orders a month with one or two offers, the free tiers of Shopify Bundles, Bundler, Selleasy and MixMaxer are plans; the others are trials with a free label.
What to check before relying on a free tier
- Does the discount apply in Shop Pay and express checkouts on the free tier? Function-based discounts do; script-based ones often do not, on any tier. Why bundle discounts fail at checkout.
- Is there branding on the storefront? Some free tiers add a "Powered by" line to the widget; check it on a product page. MixMaxer shows no branding on any plan.
- What happens at the cap? Offers switch off, or a bill arrives? Pumper and Rapi move you to the next tier; BOGOS stops at 30 orders until you upgrade.
- Can you measure the offer on the free tier? Without a visitor split or a holdout you cannot tell whether the offer added anything. MixMaxer's free tier includes one A/B test with automatic winner and profit per offer; most free tiers include reporting only.
When you outgrow it, what the next step costs

FAQ
Is there a completely free bundle app for Shopify?
Shopify's own Bundles app is free with no caps, for fixed bundles and multipacks only. Bundler's free tier has no order or revenue cap but gates mix & match behind $9.99. MixMaxer's free tier runs two live offers of any type with no order or revenue cap.
What does "free to install" mean on the Shopify App Store?
That installing costs nothing, while the tiers you would actually run on are paid. Fast Bundle, Kaching and Rapi use the label; "Free plan available" means a tier you can stay on.
Does the free plan limit orders or revenue?
Depends on the app: Pumper and Rapi cap attributed revenue, BOGOS and Simple Bundles cap orders, Selleasy caps campaigns, MixMaxer caps live offers (2) and running tests (1) and never orders or revenue.
Which free bundle app supports volume discounts (quantity breaks)?
Bundler, Selleasy, Pumper, Rapi, Simple Bundles and MixMaxer include volume tiers on their free tiers, each within its own cap. Shopify Bundles does not do quantity breaks.
