The water in Wales tastes delightful.In fact when I've been away to England or Tenerife which are my usual holiday spots I can't wait to have a glass of welsh water. Everything else is just blurgh.

Great for homebrew ingredients, thanks.

more likely to get cancer from bottled water as the toxins seep into it from the plastic

I've been drinking tap water from birth in a city so filthy, digusting, and heavily poluted, London. And I got no cancer.

That's mental - although I doubt I would get through it all in 3 days. Or if I did I'd need to have a marathon drinking session when I'm not working as I'd be visiting the toilet every half an hour.
As for those "cheaper from the tap" people, I live in a flat with what one plumber told me was probably a shared supply pipe. The water here tastes AWFUL, and this is WHY I sometimes buy bottled water as a treat. If my tap water tasted half decent I would never buy bottled water. Simple as that.

Hot from me great price.

I prefer the concentrated water and just dilute what you need.

free from my non-metered tap.

No, the container is not even worth 28p!
