I have mentioned on this forum a number of times that some of the fixed prices were simply wrong......
This has occurred for a few years.
Some were extreme ie $2 pari versus >60 fixed but those occasions were probably software lockup errors or no one at the wheel as the vice versa occurred too.
Still we had to put up with a snow job for a time.
Wife of a book maker hired ... and pricing manipulation occurs .... call me a cynic but this was bound to happen.....
