^^ At .30 per package ALL couriers would be sleeping in tents.
To survive in a big city you probably have to make $80 and up every day (after taxes).
If each package takes 15 minutes on average, you would have to deliver about 32 packages per day to make a living at $4/package. The faster you are, the more you make

hence the craziness of the couriers.
$4 sounds fairly doable as the company may charge the customer $8-$10 depending on distance etc.
Guess this is the wrong place to discuss couriers as I'm sure there's more of them in the FG and SS forum.
