Have you seen the new milk jugs yet? I've seen them on the news but have yet to see any in my local stores. I've heard Wal*Mart and Sam's are carrying them. I just don't buy my milk there.
Anyways, I guess there's controversy already. Consumers are saying they don't pour very easily. They say they don't like the way they look. I say, get over it! I don't think it will be that hard to get used to.
And why change the shape of the milk carton? Stores are saying that they can stack these where they weren't able to do so with the old shape. By doing this, they can ship 50% more per delivery truck. That saves on gas. And since they can be stacked on top of each other, they can stop using the milk crates.
So, this is an energy efficient design where the benefits outweigh the hassle of learning to pour from a new carton or just wanting to stick with the old design because it's what we're used to. Change can be good.
