The price difference gets even bigger with smaller amounts in Estonia: 1l carton €1.15 1l plastic bag: €0.79 This is the same milk from the same producer from the same store. On a shelf these two products will be next to each other. Same store also sells a €0.59/l milk in plastic bags that basically tastes identical. (They probably buy it from the same place the others do.) So if you're shopping cheap you can pick the €0.59/l or €1.15/l milk here.
