> Also, don’t assign a EIP to your EC2 NAT instances (unless you absolutely must persist a given public IP) as that counterintuitively routes through public traffic. Just use a auto-assigned public IP (no EIP).

Could you point me to somewhere I can read more about this? I didn't know there was an extra charge for using an EIP (other than for the EIP itself).

I'm highly skeptical of this claim as well. Going through NATGW with EIP or auto-assigned IP is the exact same cost for the actual traffic.
