My weekly bill for a home of 3 is $60-$80. I got it down by doing a few tricks. I list these tips on my blog
I started by making my own bread, pancake mix, pasta, muffins and cakes. With a $5.00 10lb bag of flour, I can make 20 loaves of bread for about 50 cents a loaf.
My family also uses alo of cheese and I was spending about $12.00 a week on sliced, shredded, cream and sticks. Now I just buy a 1lb block for $5.99.
I also make my own laundry detergent and dishwasher soap.
I always buy dented cans and reduced produce. We eat meat once a week and my husband hunts pheasant. Gardening saves alot as well as you can freeze and can. I also try to make meals that can be made into something else later like if I have a rice and bean dish with veggies, I turn it into a enchilada or quesdillas.
