I see what you're saying....I haven't looked them up. But I have to say, a lot of what we eat is of dubious provenance anyway, especially sausages! If you don't buy them from the butcher's and ask what exactly is in them, chances are they'll be made of fat and scraps! The difference between �1 "sausages" and 26p "sausages" is going to be almost infinitesimal anyway, in my opinion.
Sausages here don't even look like sausages, from my experience! A pale pink, bland affair, wih no proper meat to be seen... Blurgh....
