Finally. An Extension For Safari That Prevents App Store From Opening Automatically

nomoreitunesWhenever you visit an App page via Safari, it leads you to iTunes on your computer. Finally, an extension has arrived for Safari that prevents this from happening. With NoMoreiTunes, you can easily prevent App Store and iTunes pages from opening using the desktop App. The extension disables the script that triggers that action.

Very neat and highly recommended. Get it from here.
