Family of 4, two boys, last year we came in just under $7000, or $583/month.
I live in a fairly HCOL area (So Cal).
We eat a pretty healthy diet - a lot of fruit and vegetables. Basically, I aim for 5-9 servings a day (about 1.5 to 2 lbs a person), which means I'm prepping more than 30 lbs a week.
We used to have a CSA that closed due to the drought, so we switched over to produce delivery from the farmer's market. A bit more expensive, but I don't care. That is $40-45 a week, but is only part of our produce budget.
I could cut that in half by going to the market myself AND buying produce only at Sprouts, Costco, and the 99 cent store. But honestly, we grow the stuff here, it's fresh, usually organic, tastes better, and lasts a lot longer. So, why wouldn't I buy local? Also, the box is much less wasteful from an environmental standpoint - no plastic, the produce comes in a cardboard box that is reused. We store our produce in reused plastic bread bags.
Aside from produce, I make 2-3 big meals a week. Usually one of them has beans and/ or rice. About 2x a month pasta with sauce, veggies, and meatballs. Usually one of the meals each week has meat sometimes two. We make beans & rice, fried rice with stir fry, roast chicken, chicken curry, lentil or bean curry, chili, spaghetti and meatballs, soups. Our emergency meals are frozen pizza or veggie burgers. About 2x a month we have wild salmon. I'd like to have it more often, but eh.
Shopping-wise
- I supplement our produce box with loss leaders from Sprouts
- I buy oats, brown rice, barley, dried beans in the bulk bins when they go on sale (Sprouts, Smart and Final)
- I make my own muffins, and found that one of our stores with bulk bins has gluten free Bob's Red mill mix for $2/ lb. I can't eat wheat.
- Usually I make bread for the rest of the family
- I know where to get eggs, because we eat a lot of them
- I have a "price book", but it's in my head now, so I know when things are on sale and when to buy them.
- The above means I do shop at about 7 different stores, but certainly not every week.
-- For example, gluten free pasta is cheapest at Smart and Final, same with rice. But honey - I will only buy local honey, and that I get at the farmer's market.
Also important to note: starting last September, both my kids get free lunch at school. That helps the budget a bit. They are 12 and 5.
It's a lot of work to keep the budget this low, considering the amount of produce we eat and dietary restrictions (no wheat for me, also cannot eat many carbs at my age and maintain weight). A couple of years ago, I came in under $6000, but that was shopping for produce almost exclusively at 99 cent store. I'd rather get the local stuff.
