Why are beer/drink delivery service not popular in the states?

My moms German, and she has a man come around every other week or so that drops of cases of Fanta, Coke, Mezzo Mix, and various beers. He takes the empty cases when he leaves and i assume its a subscription type of payment.

As far as i can tell, we have nothing like this in the most areas of the US. Why is that? I think thats an awesome service.
