Also that you should store things at home like they are in the store, and apples are never refrigerated at the store.

I would suppose the grocer's tradeoff is slightly different than yours. For them, it ought to be about trading shelf-life extension against refrigeration costs. For me, I'd rather extend the shelf-life of the apple even if it costs more to refrigerate it than it would to buy a new one, because I dislike throwing out food. I even freeze some produce that is about to go bad if I don't have an immediate plan for it.
