Let customers build their own bundle.

What it does

Everything you need to ship bundles, nothing you don’t.

Real discounts, real theme integration, real speed budget respected. No draft-order tricks, no external scripts.

01 / Storefront

Build-your-own bundle

Customers pick any mix of the products you choose — up to 20 — on a dedicated Build-Your-Bundle page.

02 / Psychology

Tiered discount progress bar

A live bar and “add 2 more to get 10% off” nudges push the basket up, then celebrate when the top tier unlocks.

03 / Checkout

Real automatic discounts

Discounts apply through Shopify’s own discount engine at checkout — no codes, and Shop Pay keeps working.

04 / Performance

Zero speed impact

The widget is a native theme block — no external script tags injected, so your Lighthouse score stays put.

★ / Two-minute setup

Set it up once, in the editor — free, forever.

Pick products, set your tiers, tweak colors and labels, and watch a live preview react. Add the block to a page in the theme editor and publish. No plans, no usage charges, ever.

Add the block

Drop the Bundle Builder block onto a page in your theme editor. A dedicated “Build your bundle” page works best.

Questions

Before you install.

Yes — free forever. No plans, no usage charges, no hidden fees. Every feature is included from the first install.
No. The storefront widget is a native theme app extension — Liquid plus one small vanilla JS/CSS file — with no external script tags, so it doesn’t hurt your Lighthouse or speed score.
Yes. Tiers are applied by a native Shopify automatic discount (Shopify Functions) — no discount codes and no draft-order hacks, so Shop Pay and your analytics keep working normally.
No. You add the Bundle Builder block to any page from the theme editor and set everything up inside the app — about two minutes, no developer needed.
Up to 20 products per bundle, and you choose exactly which products qualify and what the discount tiers are.
None. The app stores only your store domain and the bundle settings you create — no customer personal information. See our privacy policy.
