Same reason Amazon can run Fresh. If you order groceries and your neighbor orders an Amazon package, just pocket the money that would've been paid to a carrier to deliver that box and get your Fresh driver to do so instead.
In city areas it is possible to make up to 8 deliveries per hour.
In suburban areas it is possible to make up to 4 deliveries per hour.
In rural areas it is possible to make up to 2 deliveries per hour.
If you assume about $14/8 that's about $1.5 cost during prime times.
