I had some queued at 0.2c that got hit and also a smaller purchase 0.25c. A few brokers will give you the option to buy at the centrepoint if you shop around. I just open the buy ticket, choose CPmarket, type in 0.25c in this instance and send the order. It's hidden liquidity but centrepoint trades are a good option to have, particularly when the price is sub 1c.
