Theme Pricing Guard + Sale Badge Fixer

70% Confidence Large Market Medium Difficulty $5k-15k MRR Updated Feb 15, 2026

The Opportunity

A plug-and-play theme app extension that normalizes price, compare-at, and variant price display across themes. Auto-adds sale badges and supports $0 variant ‘Contact us’ messaging.

"Themes often mis-handle variant pricing/compare-at prices, breaking sale flags and confusing shoppers; merchants also need ‘Contact us for pricing’ for $0 variants."

Detailed Analysis

Proposed Solution

Inject a lightweight SDK to standardize price rendering and sale logic, restore compare-at visibility, auto-badge sales, and swap $0 prices for a configurable CTA with link at variant level.

Target Audience

Merchants on older or customized themes (OS1 and OS2) with pricing display issues

Competitive Landscape

Sale & Discount Badges apps, Call for Price apps, Code auditing services

Implementation Notes

Theme App Extension with DOM hooks for price blocks; listen to variant change events; compute sale/compare-at rules; render unified components; per-template toggles; exclude collection tiles if desired; zero-price rule by product/variant metafield; compatibility tests for Venture/Minimog/Trade; no core theme overwrites.

Evidence from Merchants

Real quotes from Shopify community forums

"I’ve recently started using the compare-at price field to show items that are discounted. When I first used it about a month ago, it worked great. Both prices would be shown on my collections page, and the discounted items had a SALE flag showing on the image. I loved it."

- Texas_Woods

"I’m trying to customize my Shopify store so that on the product pages, if a variant has a price of $0, it displays a message saying 'Contact us for pricing' instead of showing the $0 price."

- EonSupply

"When you go to the Natural Beans page, you will see correct pricing for the default variant - 500g. If you change the variant to 1kg, the ‘compare at’ price at the top of the product page updates, but not the price itself."
