Knowing the full price of a product, including tax and shipping costs, is extremely important to buyers when making purchase decisions. To provide our users with this information, we recently started including tax and shipping estimates on Google Product Search results in the U.S. You will now be able to see tax and shipping costs displayed alongside the product listings for which merchants have submitted this information. As the holiday shopping season progresses, we strongly encourage you to start submitting tax & shipping data for all your products if you haven't done so already. It's a great way to maximize the visibility of your products during this critical shopping period. Here's more information on how to do so.
