Where can I get Sarah Palin and John McCain masks?

US elections are on November the 4th. Bonfire night is November the 5th (or the nearest Saturday as the tradition has become). Whichever way the election goes I think the burning of McCain/Palin effigies will be appropriate.

Also, as Trick or Treat has become so popular, where can I get a Ghostbusters costume so I can chase away annoying children at the end of this month?
