@hypolite That's a great idea. Also, if the shop is nearby, you can easily go multiple times per week so you don't have to do a week's groceries at once. I sometimes walk, sometimes I take my cargo bike. And I've gotten pretty good at stacking ridiculous amounts of groceries in my arms so I can just carry it to my bike without even using a bag. But I admit that's a bit weird.
