We are starting to top over $500 per week on groceries. It seems as soon as I buy groceries, everything is gone. I limit convenience foods because that is the stuff that goes the fastest. I usually buy a few things the kids want a couple of times per month and when it is gone, it's gone. Even though almost everything I buy needs to be prepared, it still disappears. I am going to have to find a way to cut back. I am not sure how though.
