Radius Bundles: Smart Product Bundles for Shopify

Bundle Types

Five Bundle Types. Endless Ways To Boost AOV

Pick the mechanic that fits your store. Every type lifts average order value and runs natively at Shopify Checkout.

Fixed Bundle

Sell curated sets of specific products at a single price. Perfect for gift boxes and starter kits.

Buy X, Get Y at a Discount

Buy one, get one free or discounted. Drive urgency with the classic promotional offer.

Buy X, Get Y Free

Buy product X to unlock a discount on product Y. Best for accessory cross-sells.

Volume Discount

Tiered discounts that grow with quantity. Move stock and reward bulk buyers.

Newest

Mix & Match

Let shoppers build their own bundle ("pick any 3 for $50"). Define groups by hand or source them from a Shopify collection so membership stays in sync, set a minimum and maximum pick per group, and choose from five storefront layouts.

Runs inside Shopify checkout

Zero theme code

App Block + App Embed

Shop Pay safe

No payment-flow conflicts

Theme-agnostic

Swap themes without setup

Storefront Templates

20+ pre-built widget layouts. Pick one and ship.

Every template is mobile-responsive, theme-safe, and fully customizable. No theme code edits, ever.

Settings & Customizer

Every dial you'd ever want. Zero code required.

Style the widget, configure cart behaviour, and translate every shopper-facing label. Live preview, responsive overrides, save and re-apply with one click.

Appearance

Colour, typography, radius, spacing, shadow depth. Match your brand.

Cart Behavior

Redirect to cart or checkout after adding, priority strategy, discount stacking, and hiding third-party payment buttons.

Labels & Translations

Override every shopper string. Auto-translates to active storefront languages.

Custom CSS

Scoped CSS for when the customizer isn't enough. No theme leakage.

Also in settings: product cards, buttons and badges, the cart banner, responsive layout, stock limits, privacy, performance and tools.

Built for performance

Every feature merchants ask for. None of the bloat.

24 features in four groups. Start with the highlights.

Bundle as a Product

Sell a bundle as its own Shopify product, with variant choice and one cart line or separate lines. Your call.

One Cart Line

A bundle reaches the cart as a single line through native Shopify components, or separate lines if you prefer.

Rust Discount Engine

Shopify Function in WASM. Native checkout discounts with no codes and no hacks.

Variant Pickers

Shoppers pick a variant inside the bundle: buttons or dropdowns, one picker or one per option. Sold-out marked, total updates live.

Stock Sync

Bundles pause themselves when a component sells out and return when it restocks. Delete a product and the bundle pauses too, naming the item that went missing.

Sidekick Tools

Five tools for Shopify’s own AI. Search bundles and their results over any period, find the bundles a product is in, check a widget is live, and start a bundle from chat.

Offer Rules

Minimum order value, a cap on the discount, and a limit on uses per order, set per bundle.

Free Shipping

The same Rust engine discounts delivery, not just line items. Free shipping applies at checkout.

Scheduled Bundles

Set a start and end date in your store’s timezone. Bundles go live and pause themselves.

Multi-currency

Fixed discounts and widget prices convert to the shopper’s currency in every Shopify Market.

Cart Drawer Refresh

The theme’s cart drawer and cart count update after an add, on any theme.

Admin Product Page

Shopify shows what a bundle contains on the product page itself, with a link back to edit it.

FAQ

Quick answers.

How is the bundle discount applied? Is it a discount code?

No code needed. The discount is built into Shopify's checkout via a Shopify Function. When a customer has all the required products in their cart, it applies automatically. Works with Shopify Payments and Shop Pay, with no theme changes required.

Will it slow down my store?

No. The widget loads asynchronously via Shopify's App Block system, deferred so it never blocks your page from rendering. Discount logic runs server-side in Rust/WASM, so there's no checkout latency.

Does it conflict with other discount apps?

It plays well with Shopify's native discount system. One setting decides whether bundle discounts stack with your other discounts. Other Function-based apps coexist if Shopify's combine rules allow it.

What's the difference between bundle types?

Fixed Bundle: Specific products sold together at a set price. Great for gift boxes.

BOGO: Free or discounted reward when a qualifying product is bought.

Volume Discount: Bigger discount as quantity grows (buy 3, save 15%).

Buy X Get Y: Buy X to unlock a discount on Y. Cross-sell accessories.

Mix & Match: Shoppers build their own bundle from groups you define ("pick any 3 for $50").

Do I need a developer to set it up?

No. The widget is added as a theme App Block. Drag it into your product template from the theme editor. The customizer handles all styling without code.

Can I cancel anytime?

Yes. No contract, no minimum term. Uninstall from the Shopify admin anytime. The app is completely free, so there's nothing to cancel.
