K it's not weird it's more convenient. We have a pitcher, and then we have like 6 bags in the fridge. When we're done with one, we throw out the bag and we have another one all ready in the fridge to take out and use.
I honestly cannot stop laughing at that HAHHAHAHAHAHHA omg? I do not understand this bag milk? /// as an American I never heard of bagged milk or water before this post! XD I don't mean to sound stupid, I've just never heard of it!
