It means my fridge can be smaller because I don't need to keep as much in there. It means it is really easy to shop whatever is on sale - I have two grocery stores near me. I rarely have vegetables that go bad because I can just buy the stuff I need. I can just stop on the way home from work if I'm working the day shift.
I did this for a while when I lived in the states, too, in a small town. I had a similar experience, but it was far less convenient and really only doable because I was in such a small town and lived alone.
