It walks through an example cart and shows the most cost-effective store first (for instance, Sprouts in Daly City), with item-by-item breakdowns that update when quantities or options like organic bananas change. The developer discusses the main challenges of scraping store prices from different websites and normalizing units of measure, using DoorDash as the scraping source and USDA.gov data to convert items to base units like ounces. The system reports a 95% scraping success rate, covers 48 stores (mostly in the Bay Area, some in Southern California), and has 32,000 normalized products in the database."}
