Can I do it??

I am determined to make my self-imposed grocery budget this month. I budgeted $525/month for everything purchased at a grocery store - food, cleaning supplies, toiletries, diapers, etc. It's almost $17/day which seems like a lot of money and it's not a lot. Will I make it? It's Jan 22, and I have spent $444 so far. That leaves $81 for the rest of the month - almost $9/day. We go through a gallon of milk every day, so that's about $3.25 right off the top. Yikes. I need to go count Sarah's diapers.
