For starters there is a wrapping div with class "frame" that has 0 height and serves no purpose as the child element of .frame is .inner which is positioned absolutely for no reason I can tell either.
In the div .headlinks everything is floated left except div .minicart has a margin to give the links room, then again the table used to position the thing bag and login links.
The "oddness" I mentioned though was all the margins and absolute positioning on the different sections, which I now presume is to position the content before the header and navigation links in the HTML, so okay, I can get behind that kind of a thing for SEO and whatever.
I just found the whole thing is very pixel dependent and a change in the text/copy or the font size could throw the whole layout out of whack in places. But you know it's just a style different than my own, and if it's working, best to ignore me.
