Oh dear, that doesn't bode well then I've just done a search and found posts where they were listed as 0.5 syns each of EE/Red. SW must've reviewed them according to your post.
Which day did you select at the top of the page? Last time I looked at that (at the weekend) it still had 1 for premium and 1/2 for the 8 pack sausages!
I just made a casserole for tea with the weight watchers ones, and nearly had a little cry when i thought they were 3.5 each! deliberatly paid the extra £1 for them cause the thought they were lower! phew!
