A Co-worker noticed that the idea of having a link to buy MacOS X software right there in the Apple menu was very "Microsoftish", so he tracked down where it was located and I figured out how to get rid of the menu item altogether. (I know there are other links out there to customize (in a way) the Apple menu. This simply tells how to get rid of that menu item in X 10.1.)
Warning: If you're not comfy in the Terminal and/or vi, this might not be for you. An unsuccessful attempt at this has the nasty side-effect of not allowing you to run the Finder... (yes, you'd have to ssh/telnet into the machine to fix it if you mess this up somehow.)
[Editor's caution: I have not tried this myself, and it's quite possible that a mix-up in the editing will render your Finder unusable. Please proceed with caution if you're going to attempt this modification! Read the rest of the article for the how-to.]
