iPhone app link : AppStore + Website or only Website

I'm currently redesigning my personal web site and I want to link to my different iOS apps. I have currently two links for each of my apps : Website and AppStore.

But is the AppStore link is really necessary? We are making web sites for iOS apps to describe it in a better fashion then we can do on the AppStore itself. So why link to the AppStore.

I understand there will be people wanting to go to the AppStore directly, they will have 2 links to click. Is worth it?
