Css to move price & add to cart button down on grid layout

Hi Guys,

I'm currently tidying up marketpress installation for a client and we're nearly done, but one bit of css eludes me!

I need to expand the area available for the product title in the new grid layout. I'm using the built in shortcode to display a grid of all the products in a category which looks great. The only issue is if the product title is quite long, it overlaps the add to cart button.

You can see it in action here: http://adhpublishing.com/shop/store/books/slot-racing/

I've tried using the css inspector in chrome but I just can't seem to find the css selector to move the price & buy button down.

Can anyone point me in the correct direction please? Either that, or can I limit the product title to display a set number of characters in the grid?

Thanks in advance
