### Before submitting

- [x] I searched existing issues and did not find an equivalent request.

No files, tests, or entry points are identified. First compare a scraper with an API-based approach for obtaining current product prices, then inspect the repository to locate the existing price-tracking flow. Done should mean the app reliably retrieves and displays up-to-date prices, but the source, products, and acceptance criteria still need definition.
