>This is another odd market where somehow the US incumbents seem unable to implement an obvious feature that is common in other countries. This is not quite correct. Grocery stores have had delivery in large cities for a while. There's even a pretty famous scene in the movie Magnolia (1999) that revolves around it. The US is big, and has a lot of empty space, and has many different markets that are tough to coordinate. It's no surprise then than it has taken a big player like Amazon to offer wall-to-wall coverage of grocery delivery. It still hasn't been proven to be something a sufficient number of Americans even want.
