It then creates a list of the cheapest version of a product from each website and provides the link to that product.</p> <h2> Use Case &amp; Impact </h2> <p>Anyone who buys anything online would greatly benefit from switching from having to search for hours for the cheapest version of a product to just 2 minutes, as Runner H does the searching for you. </p> devchallenge runnerhchallenge ai machinelearning
