It's enough for the costs to be internalized by consumers.
Broadly speaking, I think people prefer to spend less money on equivalent goods. So, yes. I do.
I think the effect will probably be less strong than if the entire cost were concentrated at the point of purchase.
But really though, there have been weeks where we filled up our bin with lacroixs and beers and I stopped buying canned beverages because of that(for the next 7 days)
Its more environmental laws and how strict regulations are about seepage.
