I was wondering where you live?
There are only two in our household. Produce is the biggest part of our grocery budget.
I average about $350 to 400 a month for groceries & household necessities. I live in Indiana. Since most of our stores and products are national, I think our prices are the same as everywhere else. The only thing cheaper here is housing. This time of year, we grow tomatoes & bell peppers in our back yard.
Are you cooking from SCRATCH? Are you eating in restaurants?
When we retired, our food budget increased. But then we realized that we were not eating in our employers cafeterias, and we cut our meals out to once a week.
I keep canned beans on the shelf, but I also make them from the dried state.
If you use milk: Use powdered milk when ever you can.
Frozen veggies are cheaper than fresh - just don't buy the fancy ones. Buy the basics.
You may not have as much variety.
I find that coupons are not helpful as they are only for brand name foods. The store brands are usually cheaper. Once in a while, a brand name is cheaper on cereal than the store brand.
We eat a lot of oatmeal. You can do great things with apples & oatmeal.
What are spending on cleaning supplies? Is there something you can cut.
Use shampoo sparingly. Everybody has a different situation - but I have found that I can wash my hair with shampoo every other time I wash my hair. The other time, I just rinse it well so that I can style it.
