Rich Snippits - Product Data showing in serps

[iAnalyst.com]

Google "halloween costumes", see the yandy listing that shows product data and pricing under their listing?

How did they do this? I realize its a rich snippit of some kind but i don't see in the code how or where this is. I've yet to see anyone but Amazon influence the SERPS yet with rich snippits. Pretty interesting

They're using Schema, rdfa, or another microformat. Right now, there's a bit of a fight at which format will come out on top. You should look and see what your competitors are using as that will show you what the dominate microformat is in your industry, especially if you're seeing the results of their efforts on Google. A List Apart did a wonderful introduction to rdfa that really explains the whys and wherefores of microformats.

Thanks, i stil dont see what they are using. It doesn't appear to be in the code? Is there a way to check what microformat they're using?
