Sale would work beautifully in syndication as a "big money" quiz. However, the end game format would need to be tweaked. The reason the shopping end game was dropped, as is my understanding, was that it couldn't hold people's interest. The odds were, on any given day, that the champion would leave without any sort of bonus prize. The Winners Board was implimented to add a guaranteed element of suspense to the end of every episode -- there was always that chance that a car or $10,000 could be won.
The Winners Big Money Game... sucked. A fine end game, sure... on any other show except Sale. Never speak of it again in this context. Junk it. My idea is this: give the winning player a choice to either spend their winnings on a pre-selected bonus prize (something worth between $3,000 and $6,000), or spend it on a chance to unlock a "vault," which contains a jackpot of prizes (say, a luxury car or two, a trip around the world and a cash prize of anywhere between $100,000 and $1,000,000).
The vault bonus format would ideally be some sort of safe-cracker game (think the bonus from "Dream House"). The champion's odds of opening the vault and winning the jackpot would increase depending on the number of games he or she had won. The value of the prize they were offered in lieu of playing the bonus should also increase.
Mark L. Wahlberg would probably be the ideal host, amongst experienced emcees. The set, of course, would need a modern update, though the theme song should be kept similar (the theme from the Australian version of the show in the late 90s would be ideal). Long story short, I would take back nearly every nasty thing I've ever said about Fremantle Media if they revived the show and gave it the proper treatment and respect it deserves.
