My friend Angie, an avid design and sustainability enthusiast, tipped me off to the new milk jugs that Walmart is pushing. They supposedly keep milk fresher, reduce packing and transportation costs, and are more fridge-friendly.

Sam’s Club Members are reaching for a fresh alternative in the dairy cooler — a square shaped gallon that represents a packaging change consistent with the transformation of milk from pitchers to glass bottles in the late 1800’s and then cardboard cartons to plastic gallons in the early 1950’s.
