I tested that store and it seems really slow and my broswer hangs for a few secs while the new window opens. I don't really like it. Seems slower than it should be. Why is a popup window a good idea for your cart? Do you really think that makes it quicker/easier to use?
Of course, I'm just a mean computer nerd so there you go.
