二重価格・価格履歴 景表法チェック

This app automatically records price history for your Shopify catalog to support dual-price displays under Japan's Consumer Affairs Agency guidelines. It tracks the regular price and sale price for every product variant from installation, ensuring your struck-through pricing complies with the 8-week rule. The app checks each dual-price display against CAA benchmarks, flags any displays that lack proper price records, and generates joint-disclosure text showing when and how long each price was offered. Perfect for Japanese merchants who need to maintain compliant price history documentation for their sale displays. The app only accesses product catalog data—no customer information or order details.
