We don't even have a list. We just always take the same path through the store and know what we need to pick up at each spot along the way. The only thing that really throws us off is if we end up eating out with friends once or twice and then our "snacking" food runs out faster than our "meal" food. Usually we base our grocery trips on when we run out of milk though, which happens pretty predictably.
