Here are my 2 cents:
- first, the site looks a little crowded, you made it 780 pixels wide, but you might think of 995 pixels (that will work for 1024x768) I don't think there are so many visitors out there using a lower screen resolution
- second, when you click on a category, all you see is...the Google ads. You have to scroll down to see the actual products, which somehow gives the feeling that you don't have any products in that category
- I can't see any contact details for the site. Contact (even a form) is a must in establishing trust and connect to your buyers.
- the left menu should show what page are you in. So when you are in the Birds Door Stops page, this should be the highlighted entry in the menu
- logo. People are expecting to have a link behind the logo, pointing to the homepage
- auxiliary pages. You need to have some auxiliary pages
