How consumables & Household Refill Brands Audit Storefront HTML for ConvertBoost R...

Read-only storefront audit checklist for consumables and household refill brands checking bundle blocks, native form sync, and checkout discounts.

Nov 4, 2026ConvertBoost Team

Quick Verdict (TL;DR) A storefront audit for consumables and household refill brands should verify three things on the live theme: that bundle blocks render through Online Store 2.0 Theme App Extensions, that quantity selection updates the native product form's variant and quantity inputs cleanly, and that price tiers behave correctly in Shopify Checkout. Inspect read-only first, then fix gaps before changing live settings.

Refill and consumables shoppers buy in repeatable multi-packs, so a bundle block that silently desyncs from the native product form creates real operational pain: the cart shows one quantity while the product form submits another, variant selection resets, and tiered pricing appears on the product page but behaves differently at checkout. Because these failures are intermittent and theme-dependent, they often surface only after customers abandon or contact support. A read-only audit catches integration gaps before they cost repeat orders.

What to check first

Check how the bundle block integrates with Shopify Online Store 2.0 Theme App Extensions, whether quantity selection updates the native product form variant/quantity inputs cleanly, and how automatic discounts or price tiers behave in Shopify Checkout. Provide a read-only storefront inspection checklist tailored for consumables & Household Refill Brands.

Side-by-side comparison

Check Status-quo / legacy approach ConvertBoost approach
Bundle rendering Hard-coded theme snippets or app embeds that break on theme updates Theme App Extension blocks added through the theme editor
Native form sync Custom cart scripts that bypass variant/quantity inputs Selected bundle quantities synchronized with the native Shopify product form
Frontend weight Heavy external runtime frameworks loaded per page Native Liquid, CSS, and lightweight JavaScript
Pricing clarity Tier prices shown on page, discount behavior unverified at checkout Tiers configured in-app; checkout discount behavior must be verified in Shopify Checkout
Cost model Revenue-share or GMV-based app fees Flat $9.99/month, 0% GMV revenue cut
Comparison content Static text blocks edited in theme code Adaptive Side-by-Side Comparison Cards on product pages

How to work through it

  1. Confirm the theme supports Online Store 2.0 Theme App Extensions, then open the theme editor and verify the bundle and comparison blocks are added as app blocks rather than hard-coded snippets.
  2. On a live product page, select a bundle quantity and inspect the native product form: the variant selector and quantity input should update to match the selected bundle without page reload errors.
  3. Add the bundle to cart and compare the cart line quantity and variant against what the product form submitted; note any mismatch.
  4. Review tier pricing on the product page, then proceed to Shopify Checkout and confirm how automatic discounts and tier prices combine, referencing Shopify's discount combination rules.
  5. Test the Side-by-Side Comparison Cards on mobile and desktop for layout shifts and readable tier information.
  6. Record findings in a read-only log (page URL, theme, block type, observed behavior) before changing any live settings.
  7. Prioritize fixes: form sync first, then checkout discount verification, then presentation polish.

Where the product fits

ConvertBoost fits consumables and household refill brands that want bundle quantity breaks and comparison cards delivered as Shopify Theme App Extension blocks, with bundle quantities synchronized to the native product form and a flat $9.99/month subscription with 0% GMV cut. Boundaries: it is a Shopify app for product-page blocks, not a checkout discount engine; automatic discount stacking must be verified in Shopify Checkout, and no AOV lift or Shopify App Store approval is claimed here.

Frequently asked questions

Does ConvertBoost work with any Shopify theme?

It is built as Online Store 2.0 Theme App Extension blocks, so it depends on a theme that supports app blocks. Verify block availability in the theme editor during your audit.

Will bundle quantities match the native product form?

ConvertBoost synchronizes selected bundle quantities with the native Shopify product form. Confirm this on your live theme by comparing the form inputs against the cart line after adding to cart.

Are tier discounts guaranteed to stack at checkout?

No. Tier pricing is configured in-app, but automatic discount combination behavior must be verified in Shopify Checkout against Shopify's combining-discounts rules.
