There are 25Cents of Return on any plastic vessel in the EU region, that really helped a lot. I buy mostly beverages in glass vessels personally - it's just a bit unhandy if you have children around.

Drinking filtered water tap water is possible to a certain extent in my area. But the water here is overall very 'hard' and doctors warned us to mainly rely upon that. It might cause kidney stones, they said. So the mix makes a good result.

But I personally despise this plastic madness since I can think for myself. It really is madness!
