and here is a perfect example of a little knowledge being dangerous Sainsbury's and Marks and Spencer who are currently paying 34p per litre, Waitrose who are paying 33p per litre, Tesco who are paying 32p per litre and Co-op who are paying almost 31p per litre. Arla, which supplies Asda, pays farmers 25p per litre, as does Muller Wiseman. Dairy Crest is set to cut its price to less than 25p per litre, and First Milk - which recently delayed payments to farmers - pays about 22p per litre. Iceland supermarket gets its milk from Arla and Muller Wiseman on the open market but in the good times they can get 50% more than the top fixed rate.. mix into that the variables of rents rates labour costs etc etc and its far from 'low' pricing affecting dairy farmers..
