Personally i dont like those popups..
i dont understand the need to "scroll" an image of a product upon hover. especially if its the same image you see.
"Share"-text doesnt do anything on the product page
I think its better to use one-page-checkout. See VP OPC - doesnt cost a lot but makes it easier.
breadcrumbs font is not like rest of page. that is odd.
the search text-input needs a bit of margin, så that it is placed in the middle of the bar. like the menu-elements
And i must comment.. kids-stuff is expensive in norway
(also in dk, but that much)
