I need to find a better way to have water rather than lugging severa 8L water bottles from Mercadona every week.

I asked around in Ideal and Tiendaelectron in Puerto when I was in the area earlier today - neither had them.

I did find a "under sink" filtration system but at almost €200 I think I'll wait a bit longer.

Can anyone recomend any shops in the north who sell the Britta (or similar) systems and more importantly... the refils?
