I think it is personally.
If you have a Lidl near you, I recommend you get four pints from there. Milk from [B]Lidl bears the Red Tractor mark http://www.redtractor.org.uk/site/REDT/Templates/Home.aspx?pageid=1&cc=GB
which guarantees certain quality standards.
We all want quality food thats affordable and safe to eat. The Red Tractor is an independent mark of quality that guarantees the food were buying comes from farms and food companies that meet high standards of food safety and hygiene, animal welfare and environmental protection.
The cheapest place to buy milk per pint appears to be Iceland at £1 for four pints. However it doesn't appear to bear this mark. Most of the major supermarkets have milk that bears this mark but they're much more expensive.
So what do you think? Is it worth the extra 9p if you live close to one or shop there anyway?
