I think if your old enough to drive then your old enough to babysit.
If you live near a Grocery Outlet its worth the drive. They have super cheap groceries. I go and look for specials on things like cream cheese. Sometimes I can get 3 packages for a dollar because they are close to expiring and I just throw them right in the freezer until I need one. They have fresh lunch meat that is about half the price of other grocery stores. Its the first store I go to when I need to buy groceries.
