Rich Bundle Builder

• Tier-based discounting

  Set discounts that increase as the bundle grows — 10% at three items, 15% at five, 20% at eight. Tiers are evaluated in checkout by a Shopify Function, so the price a customer sees in the builder is the price they pay, with no cart-page correction step.

• Multi-step bundle builder

  Split a bundle into ordered steps — choose a base, then a scent, then a size — with each step drawing from a different collection. Steps can be required or optional, and the running total updates as the customer moves through them.

• Two layout modes

  Render the builder as a grid for browsing-led catalogs or as a compact list for configurators with many options. Both are theme sections, so they inherit your typography and colours rather than arriving in an iframe.

• Inventory-aware rules

  Out-of-stock variants are hidden or disabled inside the builder rather than failing at checkout. For bundles that must ship complete, the whole bundle can be marked unavailable when any component runs out.

• Cart drawer integration

  Bundles appear in the cart as a single grouped line with their components nested underneath, so a customer can see what they built without the cart becoming a wall of individual items.

• Build-your-own gift box

  Let customers fill a box from a curated collection, priced by how full it is. Common in beauty, confectionery, and homeware, where the box itself is part of the product and the contents change seasonally.

• Supplement stacks

  Sell protocols rather than products — a morning stack and an evening stack assembled from the same catalog, with a discount that makes the full stack cheaper than buying its parts separately.

• Fashion multipacks

  Sell coordinated outfits or size multipacks where the customer picks sizes per item. Inventory rules keep each size selectable only while that variant is in stock.

• Starter kits with a fixed core

  Combine a required base item with a customer-chosen selection of accessories. The required step cannot be skipped, so every kit ships complete.
