Am I doing it right?

I'm thinking about inflicting the most amount of loses (of reducing profits) to Amazon, so I'm always ordering one product at a time, even if I have 5 things I need to order that day. I just stretch it over 5 days. Now, I want to know if I'm helping drivers make more money this way as well. Are they being paid by the order or by the address?

Meaning, what will make the drivers more money:

1. Delivering to the same address address 4 packages at the same time (made by different consecutive orders done in the same day, but not the same cart).

2. Delivering to the same address 1 package every day, 4 days in a row.

Thank you.
