Two years into this homestead we no longer buy the following items from the supermarket:
milk (we bought two registered La Mancha dairy goats, and their RAW milk is delicious superfood)
bread (Lynette ordered whole grains and grinds them and bakes our bread, delicious!)
beef (uh, we live on a cattle ranch)
yogurt (home-made, fresh from goat's milk)
cream cheese
refreshing beverages (home bottling kombucha, etc)
hummus (Lynette buys some sesame seed peanut butter and chickpeas and blends it herself).

In addition, Lynette's been making fermented products that pique the palate and are either 1. really refreshing (KOMBUCHA) or 2. powerfoods (BEAT KVASS and KEFIR).

My fav is the kombucha. Mmmmm... fermented black tea and sugar with fizzy zing!

So it's a start. We buy all our veg from the farmer's market now, and just harvested the 500 onions, with okra growing vigorously despite the drought. Brought in a terrific crop of tomatoes, both celebrity heat-setting and Roma. Also had bell peppers, which seem to have stopped fruiting with the tomatoes because of extreme heat, dryness and wind. We water, but the stress is high.

Producing food is 10 times more rewarding than the savings alone. I've been keeping track, and with organic milk at $6 a gallon, we're still saving money feeding our six children goat milk even feeding the goats premium feeds and pampering them.

So far so good on the two-and-a-half acre homestead.

Hooray, too, that the US Senate voted to do away with ethanol subsidies! Yay! Now down with GMO!!!
