I noticed this ad using the ad preview tool in the US. It looks like the product ads which have been being beta tested for quite some time, however two images appear next to each other with their ads beside them. I wonder if this is some kind of comparison based listing where the image and price advertiser is clearly displayed. My major problem with this ad though is that it is difficult to distinguish which image belongs to which ad. If the images are clickable then this poses a problem in that a user might mistakenly click on threw wrong image, inflating advertiser costs.
Has anyone else seen this format before?
