Possibly because the delivery fee increase this time around was so small, many newsagents did not bother to change their rates. It was 20c per day, and it went to 20.5c per day which works out to 3.5c per week for Metropolitan agents, the country was a touch better from 25c per day to 25.63c per day or 4.41c per week.
Still as a result they are undercharging their seven day and multiple delivery customers.
