box is slightly too big

Hi,

I used to have my sidebar on the right, so this wasn’t a problem, even though I did notice it. I’ve just moved the sidebar over to the left and I can see that the comments box extends a little too far out. I’ve looked in the CSS, but don’t know what to change. You can see what I’m talking about here: http://www.globalgrey.co.uk/recently-added/

Any help would be appreciated.
Thanks,
Aisha
