Sale of the Century: Episode dated 3 January 1983

Three contestants answer trivia questions, gaining five points for each correct response and losing that amount for a wrong one. Unlike Jeopardy, they can ring in at any time, so speed and anticipation are key. During the course of the show, they can exchange points for prizes and money. For instance, one can exchange 16 points for an all-expense paid Mexican vacation valued at over $2,000. At the end, the winner gets a chance to cash in their points or bank it for the next show.
