Hi Bryan,
I'm asking one of our associates who works a lot with ecommerce sites to come over and add some advice to this question. You do seem to have an awful lot of navigation links.
As a side note, you might want to look at your on-site search. I saw that you had barstools with the Purdue logo, but a search for Purdue said there were no matching items. edit: change that to say look at the layout. There's a lot of white space so that the search results were shown below the fold, and I didn't realize there were actually matching products there. You might want to move that up a bit for user experience.
