Up in Quebec they sell milk cold, but in comes in plastic bags. They have molded containers in which you place the plastic bag of milk and then snip off a corner of the plastic bag. The first time I saw it, I thought it was ungainly, but it works for them.
In Sri Lanka they use Nespray, a Nestle milk powder product, and it's kept in a fridge after it is mixed. Usually, when I'm overseas, I only drink Coke or Pepsi from individual bottles.
