I wouldn't go as far to even say Amazon delivery people are in competition with UPS and Fedex delivery. Amazon's couriers (as you call them, and it seems like a good designation), practically work the last mile for Amazon, from the Hub, to a given customer's address. I imagine UPS, USPS (here in the states) and Fedex are still handling much of the deliveries and shipments to Amazon's hubs in the first place?
