With organic, it pays to shop around.

In her book What to Eat, Marion Nestle writes that "organic dairy foods are the fastest-growing segment of that industry….[They] brought in $1.4 billion in sales in 2003, but that figure was 20 percent higher than in the previous year." With so many new organic options, prices can vary widely. To save, look for organic store brands (the milk is likely produced by a major organic producer like Aurora or Horizon). Also, shop around―one store’s organic line may be less than another’s, or you may find a good deal from a small local dairy.
