Grocery Budget

Budgeting is not my forte, it is something I am constantly evaluating and trying to perfect. I saw this link on a friends website, its an ebook about how to keep a grocery budget, for a family of 4, to $250. Seeing how I am feeding 2.5 people on a higher amount, I would LOVE to be that low! I'l let ya know if I can follow this books principles and succeed in saving more money! Fingers crossed. =>
