@kjarn - well, cynic that I am, I think that they would find creative ways to inflate their costs so that not *all* the profits are going to charity. McDonalds methods are different, so probably not relevant.
Happy belated Australia Day! I remember Woolworth's from when I was a kid, but we haven't had one here in a loooong time:) We used to have $1.49 day at Woolworths and it was always packed:)
