Imagine you are a retailer who wants to write a web application listing your products (books, DVDs, CDs, etc) at the best possible price on a large e-commerce platform. But the competition is stiff, and they’ll often set prices for the same products only a few cents lower than yours so that their offerings will appear at the top of a page of search results.
