We're pretty lucky, we have a little market (Sprouts) that carries most of our short term needs like produce, milk, some meats and it is less than a mile away. Other than produce, some of the prices are a little higher. We often just walk it and bring the kids in the wagon, but now that we have a Trek kid trailer, we've been taking the bikes more. We have two regular grocery stores about 1.5 - 2 miles away, but both are 150 ft climbs and so we are less inclined to go there. However, we do a once a month big haul at the commissary on the local base which is about 10 miles away. For that, we still use the car and fill the trunk to the max.
