Groceries. For a family of four (4). On a bicycle. Sure. How many times a day do you make the trip?
I may stop by a store again during the week for a smaller trip if there's something I really need, or pop to a corner store if I need to grab something like drinks for guests, but it's not out of my way.
It's really not a big deal. Bike panniers can hold a ton.
>short of a rickshaw you ain't getting all of that on a bicycle with or without panniers
Four Americans, maybe.
