If you have to deliver a parcel anyway, why delay? In the UK Second Class post is just held back a bit. It isn't like it gets sent by pack horse instead of by truck. Now you are a good sort, but your neighbour might be on the phone to them on Sunday evening saying 'I ordered this Friday, moan, moan, moan...' if it was not delivered so promptly. This would incur 20 to 30 minutes of customer service time and could possibly lose them as a customer, for them to write negative reviews and bad mouth the company. It is less work to do deliveries really promptly and have no queue to manage. Don't feel bad for the people that work to achieve this, imagine how much more miserable they would be if they had a backlog, a veritable mountain of stuff to deliver on Monday, for them to not get it all done and to be going home fretting about it. I am no fan of Amazon but I can see what they are doing.
