Looks like there's an unclosed tag or a typo in the CSS file somewhere...


EDIT: I found the culprit! There used to be an ad just below the dark blue nav menu at the top of the page. The space where the ad used to be was surrounded by DIV tags. That spot is now missing the closing DIV tag.

Here's the problem section:

<div style="margin-left:auto; margin-right: auto; text-align: center"><!--freeshippingdiv-->
<!--endoffreeshippingdiv--></div>


That last </div> isn't currently there, but should be.
