Price comparison websites are online tools that help consumers find the best deals on products and services. By entering a specific item, like a smartphone or hotel, users can quickly see prices from various retailers or service providers. This makes it easier to compare options and choose the one that fits their budget. These websites often include filters to narrow down choices based on features, ratings, or location. Some popular examples include Google Shopping and Kayak. By using these platforms, shoppers can save time and money, ensuring they get the best value for their purchases.
