FilmPro sells millions of videocassettes directly to consumers at $25 apiece for a $10 profit on each  However, FilmPro is losing money because people are buying illegally copied versions of its $25 videocassettes at far cheaper prices  So far, one million illegally copied cassettes have been sold for $5 each
Illegal copying, ttherefore, has cost the company at least $10 million in potential profits
At least one million more cassettes would have been purchased from FilmPro for $25 apiece if the illegally copied cassettes had not been available.
