Consider this ...
Darwin hold $100,000 on a race. $90,000 is to be paid in winning bets so the house profit is $10,000. But Read's mob only pay out $85,500 after the 5% rip which the increses their profit by 45%!!!
Wouldn't you love to find a way when on the punt that you could increase your winnings by 45%? That's like getting 6/4 about every 1/1 winner.
As Reenster points out, there are plenty of competitors offering no take-out top flucs ... now that the Vanuatu boys have hit town I think Mr Read might sharpen up a bit.
