I think that depends on what your trip from home to the store is. Is it a pleasant 10 minute trip on down a country road or in an exciting, bustling city, or is it a 10 minute trip along a despotic road with nothing going on and which screams "cars only! no humans allowed!"? I prefer getting smaller grocery loads more frequently when the store is nearby, but when the trip is an ordeal, you go fewer big trips to avoid that as much as possible. A pleasant 15-20 minute walk to a store is much nicer than a 10 minute drive through an oppressive roadscape.
