B.A.
It worked great when I was a working mom b/c I took advantage of all of the "convenience foods" but now that I am a SAHM and cook alot from scratch I don't use it much at all. Coupons can be great...especially if you use a store that doubles them.
I've learned to "Stock Shop" rather than just buying what I need for the moment and find some really great sales. Like, if you see frozen carrots on sale buy a few more bags than normal for the great price...I buy alot of canned goods and purchase about 5 cans every time I go to the store. I also buy things like bagged noodles, dry beans and bag rice...all pretty cheap to keep on hand for those weeks when money is a bit tight. We love Red Beans & Rice, Chicken Noodle bake and others that are only a couple of dollars to fix. Hope this helps a bit.
