> It arrives when it arrives.

Yeah, but will I be at home when it does? We no longer live in a world where everyone has a nuclear family and the wife is always home while dad is at work. In 2026, only the rich can afford a housewife.

Most of the time I am indeed not in a hurry to receive my purchases. For most items I genuinely could not care less if it arrived tomorrow or two weeks from now. But I do need to know when it will arrive, so that someone is home to receive it.

"A month from now, on a Monday morning" versus "A month from now, on a Tuesday afternoon" makes a huge difference for me, as one of them would result in me having to walk to my front door and the other would result in me having to rent a car and spend an entire afternoon having to go to the other side of the city to pick it up at some warehouse.

90% of the time I choose next-day delivery it is because I know I will be home tomorrow, and the alternative is "some random day next week". If they offered me the option to pick out of a bunch of guaranteed delivery moments next week which are convenient for the seller/shipper, I would!
