How often do you food shop? and how often

For food, I shop once a month at Walmart. 

What kind of stuff do you mean?

I food shop on an "as needed" basis, and I'm very fortunate to be able to do most of it in my immediate neighborhood. There are several independent produce stores, within a few blocks, and they all sell grains, pastas, dairy, oils and other staples - and, at much better prices than the supermarkets. There are some bakeries, and European markets, that sell wonderful hearty breads and ethnic foods. And, I like the local meat/fish stores. (There's no shortage of nearby stores that sell nice wines. )

I only take the car to the "supermarket," every couple of weeks, or so, for some canned/jarred items, household goods ... and my jug-wine for my daily sips. Hey, I can't watch the evening news, without a "hit."

I eat out, randomly. That's mostly with neighbors, at close-by places. As I said, in another post, late afternoon small meals are becoming more common than larger meals. Sometimes, afternoon outings are combined with lunch. On rare occasion, I decide to eat breakfast out.

Chinese delivery and Sam's Club for essentials and snacks. Soda, seltzer, pickles, canned soups at supermarket. I can go a month between shoppings.

Not if there is any other food available.

Don't be sad. Foodgistically, I'm relatively happy.

I usually store them in the refrigerator.
