a lot of it used to go to feed animals but since BSE they havnt done so
i dont think the giving away thing would work either as some one pointed out people would wait just as they now do for the discount stickered food
they could cut back on stock but then if they ran out at any time there would be more shouts about that than any praise for ensuring no waste
though if we make sure we use up all what we buy the stock levels would get reduced as the shops noticed the lack of buying of that stuff
i see it more of a problem for us all than just the shops and belive me i am rarely on their side
