We found another great way to save money is to meal plan. I buy our meat in bulk, and plan off what I buy on special. I buy as much fruit and veg in bulk as I can too. We are a family of 5, and two dogs. I cook most of our meals from scratch, and avoid packaged food as much as possible, including dog food.
Also, times like this (school holidays) I find lots of fun, free things to do. Our local library has plenty of free activities!
