Thanks to Chris Harvey who passed on a link for the Pipeline Card. This is just a concept at the moment that has been agreed in principle with a major petrol retailer which could see consumers saving 5-10 pence per litre on fuel. However there is a but! - enough (<100k) have to register before the scheme can become a viable proposition - so take a look at the website and see if you think it's a neat idea.
