I doubt they can get shipping cheap enough to make much of a dent in local supermarkets. Music and books can be downloaded. Kitty litter, not so much. Spend 10

I doubt they can get shipping cheap enough to make much of a dent in local supermarkets. Music and books can be downloaded. Kitty litter, not so much. Spend 10 minutes outside of a typical suburban grocery store and try to estimate the weight of everything coming out. Will it be used? Sure. I think it's more likely that it will push grocery chains to start/improve their own delivery services. After all, they already have "distribution centers" all over the place.
