Features

Everything you need to sell more per order.

Five bundle types

Fixed bundles, build-your-own boxes, volume discounts, mix-and-match, and frequently bought together — all from one admin.

Real Shopify discounts

Bundle pricing runs through Shopify discount functions, so the price the shopper sees is the price they pay at checkout. No fake variants or price hacks.

Inventory that stays accurate

Stock is tracked on each component product. When a bundle sells, the individual items are deducted — no duplicate SKUs to reconcile.

Flexible discount rules

Percentage off, fixed amount off, fixed bundle price, or tiered discounts that grow with the number of items.

Design that matches your theme

Online Store 2.0 app blocks with color, layout, and text controls. Place them in the theme editor without touching code.

Box builder rules

Set steps, allowed collections, and minimum and maximum item counts so every custom box is one you can actually ship.

FAQ

Questions merchants ask before they install.

What is a Shopify bundle builder?

It is an app that lets you sell several products together at a special price — either as a set you define, or as a box the shopper builds. Foxr also adds volume discounts and frequently bought together offers.

How is inventory handled?

Foxr tracks stock on the individual component products. When a bundle is ordered, each item is deducted, so you never manage separate bundle SKUs.

Do bundle discounts work at checkout?

Yes. Discounts are applied through Shopify discount functions, so the bundle price is honored at checkout without price hacks.

Can customers build their own bundle?

Yes. The box builder lets shoppers choose items across steps, with min and max rules and a discount that grows as the box fills.

Do I need to edit my theme?

No. Bundle blocks are Online Store 2.0 app blocks you add and position in the Shopify theme editor.

Does it work with Foxr Post Purchase Upsell?

Yes. Use bundles to grow the cart before checkout, then add a one-click post-purchase offer after payment.
