I believe you are referring to me

Yes, we spend on average $75/week for a family of 5 with two teenagers.
If you had read my post, you would have seen that our dd13 has multiple food allergies. Even if I had wanted to buy ramen, I couldn't.
I do not spend money on toiletries. I "do" CVS Extra Care Bucks deals and Walgreens Easy Saver rebate deals, rolling the money from one special into "purchasing" the next, rinse and repeat. Through the use of coupons with the special deals, I actually make money which I then use on things that don't go on sale, like our contact solution and good hair products.
I shop at three grocery stores, at a Pepperidge Farms outlet (for the all-natural, no hfcs, whole wheat bread that dd can eat), at Costco (for coffee beans, dairy products, frozen organic veggies, fresh organic veggies and fruits), at CVS and Walgreens as mentioned above, at a natural foods store (for bulk spices mainly), at an orchard, at a pick-your-own farm, and at a farmers' market each Sunday at our natural foods store.
I visit
www.HotCouponWorld.com almost daily to read the accumulated wisdom of all the posters on the site (I prefer this to
www.GroceryGame.com because (1) it's free and (2) I have such a wide variety of stores in the area, including ones I don't normally shop at, that I can easily check at HCW).
I buy 4-6 newspapers every weekend for the coupons. I will trade for more when an especially hot deal comes around.
I buy what is on sale. And lots of it. By doing so, after a few months I have a great variety of food. I know how much of a particular item my family will use AND I know how often that item will go on sale, so I stock enough to last us until the next good sale. I kept a price book for years--now my price book is in my head as it's second-nature
I cook and bake almost everything from scratch. My exceptions are the Pepperidge Farms bread, flour tortillas, crunchy taco shells, and salad dressings.
Chips and soda are for parties and special occasions. Candy is for holidays (except for my secret Hershey's Bliss stash--that's for pms

)
I garden. And garden. I have five 4x8 raised beds plus an herb garden (and dh's hops), strawberries, 4 blueberry bushes, 20' of raspberries, 10' of blackberries, two peach trees and two apple trees (planted last year so not producing yet).
It IS a lot of work, that's for sure. And it's not for everyone. I began shopping this way our of necessity 10 years ago when dh made a career change that drastically cut our income for 3 years. Although our income has increased to a level that I don't NEED to shop this way, I continue to do so. Our kids are in private school, we've got good college savings, we're at a comfortable retirement savings level, we pay cash for everything, and we're blessed to be able to take an annual vacation.
So that's how I can feed my family of 5 for $75/week, average
