Please elaborate on the point about "cart screen line items weren't lined up". Which page is that?
(I wanted to post that but I guess I forgot about it.)

On the "/cart/" page the contents of the rows vertically align to the middle, so cell contents don't line up horizontally -- e.g., the prices don't line up with the first line of a multi-line product name. And the "Quantity" header is left-aligned, while the other headers are centered. Not very important stuff, really, and perhaps just a matter of personal preference.
