I agree with Miro - the darker blue is not dark enough. Also, you may want to consider extending the nav bar all the wa to the right or separating each item into a tab. As it is, it looks like one didn't load. I would add some more padding around the bottom box. The product boxes look good.

Yeah that was one thing i had also thought about, think i may give a 1px break in the menu items, or make the bar go right across.
