In America, no publisher wanted the elusive 21st chapter because it shows Alex learning the error of his ways. Publishers did not think Americans would like the "happily ever after" effect and told Anthony Burgess to take it out. so the only place you will find a copy of a ClockWork Orange with the 21st chapter would be in the U.K.
Probably. I'd go on amazon.com if i were you.
