You've seen the offers from bookies promising to "double your deposit" or refund your bet "if your horse runs second".
They're usually accompanied by a couple of asterisks pointing to disclaimers that tell you the extra $100 or the money you got back can't be used for anything, really, except placing more bets you probably won't win.
Well, the odds are pretty good that you won't be seeing as many of these deals in Queensland.
