Some champs walked away with nothing to show for their efforts, while losing contestants didn't even get their final score in cash. Several episodes even managed to give away a grand total of zero dollars.
The prizes were also generally significantly cheaper than the 1980s Sale: Instant Bargain prizes were usually around $500 to $1,000 (less than 1/4th the typical value of the prizes in the Jim Perry era if you adjust for inflation), and the top prize was just one mid-range car worth less than 1/8th the total typical Lot value from Sale (again, adjusted for inflation).
Out of Order: You'd think a show with returning champs and a growing Instant Cash jackpot would avert this on principle; however, you'd be wrong in this case. It seems the show would air consecutive episodes until someone retired, then skip to a different part of the run.
Screwed by the Network: Rossi Morreale said in an interview that MyNetworkTV put no money at all into advertising the show. (Considering how much of a trainwreck the show was, they may have made the right choice- they were likely forced to carry it because 20th Television (part of Fox, which owns MNTV) distributed it alongside Fremantle.)
