By making multiple small shopping visits instead of one big shopping trip I can ride my bike and carry everything I purchase in a backpack. This works fine for incidentals but it is a bit more challenging to do with a full shopping trip.
Many Europeans make these daily shopping trips to buy what they want to make for their meals. I suspect they have less food waste by using this method. This works fine for those in a more suburban or city setting---a bit more challenging for those in a rural landscape though---which is most of Vermont.
