Woolworths shelf disorganization.

I went to Woolworths Loerie Centre George today and purchased 4 Low Fat Strawberry Yoghurt 6 packs. I did not have my glasses with me and when I came home I saw that 3 of the yoghurt packs had sell by dates that were today 5 December with use date tomorrow 6 December. I am absolutely disgusted that Woolworths could have this on their shelf. I intend to take it back tomorrow and ask for a refund.
