How to create product bundles on the Expanse theme (checkout-safe)

Expanse, by Archetype, is a premium Shopify theme built for large catalogs and bold, image-led brands. Its strength is visual merchandising — big product imagery, rich sections, strong storytelling — the kind of design that carries a large range without feeling cluttered. On pages that lean this visual, an offer has to be placed with care so it reads clearly. This guide shows how to create product bundles on the Expanse theme, keeping every offer checkout-safe: the price shown is the price charged.

Two ways to bundle on Expanse

Shopify’s native Bundles app groups different products into one fixed purchase — a kit or curated set. It’s free and checkout-safe, but rigid: fixed contents, its own product page, and no quantity logic like “buy 2, get 1 free.”

A product-page bundle widget shows quantity offers — BOGO, 3-for-2, volume tiers — right on the existing product page, which fits Expanse’s large, single-product storytelling. That’s what the free Profit Flow AOV Bundle adds: more units per order across a big visual catalog, without building new pages.

Adding the offer block on Expanse

Expanse is a section-rich Archetype theme, so no Liquid editing is required.

1. Install Profit Flow AOV Bundle from the Shopify App Store.
2. Open the Expanse theme editor and choose a product template.
3. In the main product section, select Add block and add the app block.
4. Place it near the price, where it won’t be visually overpowered by Expanse’s large product imagery — an offer lost beneath a hero image doesn’t convert.
5. Configure your deal — a 3-for-2, BOGO, or a tiered volume discount for stock-up ranges.

Expanse’s rich sections focus on merchandising rather than quantity upsells, so there’s typically no native bundle widget to disable to avoid duplicate offers. Keep to one clear offer per product so it holds its own against the imagery.

Keep it checkout-safe

The usual weakness in bundle tools is a discount that only lives in storefront JavaScript. A shopper edits the cart, refreshes, or arrives via a direct link, and the “free” unit gets charged — or given away when it shouldn’t be. Across a large catalog, that leakage adds up.

Profit Flow enforces every offer with a Shopify Function, the same server-side discount engine Shopify uses for its own promotions. The math is recalculated at checkout, so it can’t be bypassed. What the shopper sees is what they pay — no reconciliation, no support tickets.

Wrapping up

Expanse is built to make products look their best, and a well-placed, checkout-safe bundle adds an offer without breaking that polish. Add the block, keep it near the price, and let the Function guarantee the total. For the full picture, see our hub on how to create product bundles on Shopify.
