I’m trying to accomplish a similar EDD layout as the one you have on this site, looking at the code I see that in the add-on shop you are using the (is it the add-on?) sections to display the content.
Did you modified the shortcode output or you’re taking a different approach?
Also the popup is really nice, is it custom coded or you modified the popup add-on from EDD?
I hope you can share your insights, have a nice day.
