Looks like it's the CSS; you're floating the image, though you don't need to in this case, and the rest of your formatting isn't set up to gel with it.

The simplest solution would be to just take off the float: left; on .SingleProductDisplayImage, at least for the products in that column.

No problem. You may want to focus some more in that area and try to get better separation of the different products. The current display is looking a bit rough and jumbled. Though it isn't necessarily your problem as much as it is the app's. In looking at the code, the markup for the singleproductdisplay isn't very good at all, so you kind of have to do with what you can to style it unless you're comfortable with editing that control.
