I don't intend to do this every day/every race, but here's an example of one race.

AR2 today, the winner paid $3.40 Unitab, best price (with one of our fearless internet bookies) was $3.25, and this only bet after the closing time for the race, and Betfair traded between $3.85 & $5.20, with the last bet at $4.40.

The TAB's & bookies as we know them today will soon be obsolete, or patronised by mugs only.
