Basically, I only have space for a lot of info about 9 deals - and I chose to display the 'best' 9. So when the viewport moves it checks if something better has appeared (or if one of the old best has disappeared). Deals out of the top 9 are noted by small 'dots' which you can click for more info. (Or you can paginate through results ...).
I think that those dots may not be large/noticeable enough though ... Thanks for the heads up.
