Morning, just a very quick question..

Been tinkering some more with our layout and noticed that my left column seems to 'centre' vertrically (ie does not float at the top of the container) when some products are displayed. Please follow the link to see what I mean. Just looking for a quick pointer to say what might have been altered to make it look this way..

On some products where the centre column is shorter, it sits just fine. An example is here..

Many thanks in advance for any help..
