Related products box not wide enough?

This page has related products, which you can see the issue clearly.
The products are three across, where they should be smaller and be four across as three looks really strange.

How can I make this display like this;

Product 1…………….Product 2…………….Product 3…………….Product 4
Product 5…………….Product 6

Not

Product 1…………….Product 2…………….Product 3
Product 4…………….Product 5…………….Product 6

Hi Jim,

You can try with this tweak:

-- Go to this css file: /skin/frontend/default/jm_crafts/css/style.css

-- Add this css rule:

Code:

.product-view .category-products .products-grid li.item .inner {
    margin: 2px !important;
}

Best

That’s perfect! Thank you!
