In time for the holiday season, we now support rich snippets for shopping (e-commerce) sites! As many of you know, rich snippets are search results that have been enhanced using structured data from your web pages. Our new format shows price, availability, and product reviews on pages offering a product for sale....

Either a Merchant Center feed or markup on your pages can be used to provide data for rich snippets to show up.
