Price comparison websites are online platforms that allow consumers to compare prices for various products and services from different retailers. These websites aggregate information from multiple sources, making it easier for users to find the best deals on items like electronics, clothing, and travel services. By entering specific criteria, shoppers can quickly see price differences and make informed purchasing decisions. Many price comparison websites also provide additional features, such as user reviews, product specifications, and links to retailers' websites. This helps consumers not only find the lowest prices but also evaluate the quality and suitability of the products they are considering. Popular examples include Google Shopping and Kayak.
