How much money does it take per year to raise a large family?
There's not too much data on that, but it may be cheaper by the
dozen in some ways. Being willing to buy in bulk, use coupons, have
multiple people in bedrooms, and so on, you can bring costs down.
It is mostly about choices. Google "saving money" and you will find
a lot of resources. MSN Money website has good advice, too.
