On a related note, I noticed recently google started to have a 3 line bullet points description for some retail sites. Instead of taking the meta description or the first sentence on the page, it's taking the name and price of the top 3 items listed on page instead.
To see examples of this, search for something like "cd tower" and look for target.com's link.
Anyone know how to influence google to display the search result in this way? Obviously it would be great for retailers, you get more space on the SERP (you get total of 4 lines of description instead of 2) and by listing the products you carry, it's more appealing to the user.
