Walgreens, CVS, RiteAid and some Ace Harwares are places where you can buy the clapper. How do I know this, It literally was just on the TV as I saw your question. Clap on. Clap off.
You can buy the Clapper at many retail stores. The best solution would be to check around your local shopping areas because retailers vary by area.
