I think a big part of saving $$ is also knowing what things cost to begin with. For instance, when Pathmark runs B1G1, I usually steer clear, b/c I know it actually comes out to more money per item than when the same item goes on sale. I save my coupons for items I use anyway, and when it is at the rockbottom prices.
I grew up in a house with my mom the couponer and refunder. Our garage was organized in a filing system for her "refunding" (rebates) and we were the family on the block with 12 boxes of cereal in the closet - and my brother, the vaccuum, ate it all!
I adapted her system for my family. I left a well-paying job to stay home with my daughter, and had to cut wherever possible. However, where my mom bought loads of processed crap (IMHO) I try to stick to more healthy options - organics when possible, whole grains, no processed foods, etc. If they are onsale and I have coupons, I do stock up.
To do this in the most cost effective manner, I do the following:
Of course, I have a store card and I shop the circular. When boneless chicken breast is $1.99/lb or under, guess what we eat? I buy a lot, repackage it and freeze some too.
I cook every day, and rarely eat out. This is the biggest $$ saver. I have a huge repertoire (sp?) of recipes for stuff I buy frequently (chicken, fish, bean-based meals) and I experiment so we aren't bored - Chinese dishes, Indian dishes, etc. I love
www.allrecipes.com because they allow you to do an ingredients search where you can search by what you have on hand, and even eliminate things you don't have.
We have "planned-overs" where I will cook extra and freeze some for another time. Sometimes I take leftovers and make into totally new meals - a roast chicken will make quite a few meals.
We try to stay away from HFCS (high fructose corn syrup) and trans fats, so I am always stocked with baking staples. I use my bread machine to make whole wheat pizza dough and it makes great pizza and calzones. Mozzarella goes on sale for about $1.99 (plus coupons!) and it freezes very well. Ricotta goes on sale too, and stores well upside down in the fridge. Plain crushed tomatoes (very thin) makes a good sauce, as DD isn't a huge fan of sauce anyway.
I have a Pooh waffle iron, and make whole grain waffles every week for DD, and they freeze well. They are also amazingly good. I use this recipe:

Also, if you belong to Costco, check them out - but you have to know your prices - not everything is cheaper. Chicken there is $2.79 a pound, so no bargain. But they do get in some great organic stuff (like juice boxes, which my daughter needs for preschool) and it is hit or miss. They also have fantastic prices on organic salad and other produce. No coupons allowed at Costco, other than their own.
So, bottom line is to know your prices, and decide what will work best for your family. That way you will know if you are really getting what you use for the best price.
