Unfortunately, since the store was distributed in OS X 10.6.6, people who have removed it and subsequently updated to 10.6.8 may have difficulty reinstalling it. While this is a preferred setup for many people, the App Store is almost a requirement for upgrading OS X and for purchasing some software packages, so people who have removed the store may wish to reinstall it on their systems. Doing so reverts the Apple menu and other links for the Mac App Store to how they were in OS X 10.6.5 or earlier. Since the Mac App Store in Snow Leopard was appended to the existing OS infrastructure with the OS X 10.6.6 update, its removal was relatively easy and just required users to remove the App Store program from the Applications folder.

Some people have removed the store from their systems to keep their OS free of commercial links, but doing so makes upgrading to OS X Lion or later versions of OS X much more cumbersome.

The Mac App Store in OS X is Apple's new means for delivering software and OS upgrades to Mac users.
