One thing about the Adsense thing by google at the top of your website.

Yes you get payed on a per click basis, But the ads they are putting up there, some are for selling flies at cheaper prices, Albeit poorly tied, but Some people are budget minded and might click those instead of purchase from your sight.

Nice setup on the site though! Very easily navigated and it isn't weighed down with crap(Pictures and stupid things on the homepage) making it fast.

Nice Job!
