You can now get price comparisons for any product you're interested in just by doing a Google search and then scrolling down in the search results until you see the "Shopping results for . . . " link. Click on that link and Google returns a list of companies that offer that product and pricing information — in a format that's optimized for your iPhone. Some products, such as books and electronics, also include info such as online ratings and reviews.
