Wal-Mart used to have a nasty policy of selling only the fullscreen versions of movies on DVD. Certainly well within their rights to do so, but it speaks poorly of their clientele and also means I'd never buy one there regardless of any of my other complaints.

They used to edit CDs for explicit lyrics and not tell you, too. Nice, huh? Wouldn't want to offend the person that buys the latest Ice Cube album. You never can tell when Cube might accidentally let loose with a "gosh darn".
