HOW DO THEY DO IT

I keep reading different blogs of feeding the families of 4 or 5 for $1200 or LESS a YEAR using coupons, rebates and free items. I really do not how they can do it. I use coupons, buy on sale but still spent between going out to eat and groceries $400 to $600 a month and there is only 2 of us.
We do not go to expensive places to eat, sometimes have a coupon to reduce our bill or get a senior discount.
I am adding a couple of these blogs to my site so I watch their progress. I plan on asking if they eat out and if so much how much is that amount a month. That needs to be added into the total budget. I know if we cut out the eating out I could cut ours in half. But that would not be a $100 a month would be $250 a month maybe. As I watch their progress maybe I will get some insight from these bloggers and cut my expenses some. Hope you will watch with me their progress and my progress. If you would like to be added to my watch site I would love to hear from you.
