USPS actually works well with Amazon, because amazon sometimes uses them for last mile. Somehow Amazon seems to basically deliver to the local post office, so stuff still shows up quickly but then the postal carrier brings it with other mail. For very small packages in particular this seems somewhat common where I am. Again, this is is efficient. Amazon skips the part where USPS struggles (ie, Amazon can get something moving on their network at 2AM on a Sunday), but on Tuesday the local carrier still puts it in my box.
