Let shoppers build their own bundle.

Bundle Builder turns a page or a theme section into a step-by-step picker. Each step offers the products you chose, a bigger bundle earns a bigger discount, and a summary keeps the total and the savings in view.

Billed through your Shopify subscription, apart from your App suite plan. How mini app billing works.

How it works

  1. Create a bundle builder and add its steps.
  2. Set the tiers and the discount each one earns.
  3. Place it on a page or section and publish.

An Online Store 2.0 theme. Works on every Shopify plan.

What shoppers see

  • One step at a time, each with its own products or collections.
  • A summary that stays in view with what they picked, the running total and what they save.
  • How close they are to the next discount tier, as they pick.

What you control

  • Which products or collections each step offers.
  • The tiers: how many items earn which discount.
  • Colors, words and layout for each bundle builder you create.
  • Whether it lives on a full page or as a section on any template.

Light on your storefront

Sections below the first view reserve an estimated height before they render, so the first view does not move. Every file has a size budget that our build checks before each release, and a page without the app on it does not load these files.

Built for every shopper

  • A disabled action is marked as disabled for assistive technology, not only dimmed.
  • Motion stops for shoppers who ask for reduced motion, and forced-colors mode is supported.

Questions about Bundle Builder

Can shoppers build a bundle on any page?
Yes. Add it as a section on any template in the theme editor, or give it a full page of its own that you link from your menu or a product.
Does it change my theme code?
No. It is added as a page and as a section you place in the theme editor.
Can I run more than one bundle builder?
Yes. Each one has its own steps, tiers, look and placement.
How is it billed?
Each mini app is billed on its own, through your Shopify subscription, and apart from your App suite plan. Nothing is charged outside Shopify.
