When I see a delivery coming from Amazon I know I won’t get it until 5-6PM or even later. UPS or FedEx have found a way to get it here by 10AM.
It often results in delivery delays as well, FedEx and UPS deliveries for Amazon orders are rarely late.
Maybe it’s due to more drivers and trucks, but so far I’m not a fan of Amazons delivery and would pay more not to use it.
