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

Warehouse, by Maestrooo, is a premium Shopify theme built for large catalogs with advanced filtering and search. It’s engineered for stores with hundreds or thousands of SKUs, where shoppers navigate by faceted filters and buy in quantity. That audience responds to one thing above all: buy-more-save-more pricing. This guide shows how to create product bundles on the Warehouse theme, with tiered volume discounts front and center and every offer kept checkout-safe — the quoted price is the charged price.

Two ways to bundle on Warehouse

Shopify’s native Bundles app groups different products into one fixed SKU — a pre-assembled kit. It’s free and checkout-safe, but rigid: fixed contents, its own product page, and no quantity-tier logic.

A product-page bundle widget shows tiered volume pricing on the existing product page — x2, x3, x5 breakpoints a stock-up buyer can scan instantly. That’s the job of the free Profit Flow AOV Bundle, and it’s the offer type Warehouse’s high-SKU audience converts on best.

Adding the offer block on Warehouse

Warehouse is a section-rich Maestrooo theme, so no Liquid editing is required.

1. Install Profit Flow AOV Bundle from the Shopify App Store.
2. Open the Warehouse theme editor and choose a product template.
3. In the main product section, select Add block and add the app block.
4. Position it directly under the price so the quantity tiers are immediately visible.
5. Set up your volume discount breakpoints — for example x2, x3 and x5 — matched to how your catalog is bought.

Warehouse concentrates on catalog and filtering rather than product-page upsells, so there’s typically no native bundle widget to disable to avoid duplicate offers. Across a large catalog, apply your tiers consistently so shoppers see the same clear pricing logic on every product.

Keep it checkout-safe

With large baskets, price integrity is non-negotiable. If a discount lives only in storefront JavaScript, a shopper who edits the cart or lands via a direct link can be charged the wrong amount — and correcting a big, multi-SKU order after the fact is a real cost.

Profit Flow enforces every tier with a Shopify Function, the same server-side engine Shopify uses for its own promotions. The discount is recalculated at checkout, so it can’t be bypassed. What the page quotes is what the invoice charges — clean orders, no manual corrections.

Wrapping up

Warehouse is purpose-built for large, quantity-driven catalogs, which makes tiered volume bundles a natural fit. Add the block, build your tiers, and let the Function guarantee the price. For the full range of options, see our hub on how to create product bundles on Shopify.
