A price comparison engine is an online tool that allows users to compare prices of products from multiple online shopping stores. It helps consumers find the best deals and offers by providing information on prices, discounts, and other relevant factors. In India, one such platform is tenshop which offers a comprehensive price comparison service for a wide range of products across various categories.

Price comparison engines, like Xuper Mall, function by collecting and analyzing data from various online shopping stores. They gather information on product prices, discounts, and other promotions, and display the results in a user-friendly format. This allows customers to easily compare prices and make informed decisions about their purchases.

Tenshop displays prices from over 178 online shopping stores, including popular stores like Amazon, Flipkart, boat, boult and TataCLiQ. This extensive list of stores ensures that users can compare prices and find the best deals across a variety of online stores.
