🟢find_best_total_deal(product, postal_code)

Find the cheapest price and best deal for an exact new physical product. Use for requests like “where to buy,” “price comparison,” “lowest total cost including shipping,” or “is it in stock?” It resolves the model and variant, checks current offers, shipping, stock, delivery timing, and known mandatory fees.
