grocery budget

The reality of going from DINKs to SIWKs (Double-Income-No-Kids to Single-Income-With-Kids) is still sinking in and we are rehauling our budget and reigning in our spending habits. (Y'all are getting a toothpick for Christmas, two toothpicks if we really like you.)

I would dearly like to know what is 'normal' for grocery spending. Would you mind sharing?

:: How many people in your family?
:: How much do you spend a month on groceries?
:: Do you live in a urban or rural area?
:: Do you consider yourself thrifty? moderate? spendy?

Thanks!
