Speaking as one of those people without a car: I've got a backpack.

Grocery pickup is absurdly useful. You ever had a hiking pack to whoever is bagging or try and fill it while doing self-checkout? It's not bad in all honesty but it's still more annoying than just picking it up curbside. Plus the side benefit on not whipping some kid in the face with bag straps because I turned around too fast.
