I don't know if I've ever linked to The Grocery Cart Challenge before...but it's wonderful! And it does put nails in the coffin to that idea that you can't eat well for $100 a week--check out this hsing mom who's trying to do it for $50. She admits that most weeks they're closer to $60, when you include non-food items--well, shame on her, right? Wish I could do that well!
I like her balance of trying to use what she already has and stocking up just when she's already under budget for the week--I know there are other approaches, but this one seems to be working for her family. Check it out--I like the recipe links, too.
