How often do you go grocery shopping?

I know plenty of people who have a system for when and how often they go grocery shopping. But I’m not one of them. I go when I need stuff. I like to go grocery shopping. It’s very Zen for me. I’m not sure how often I go; it’s probably 2-3 times each week. But again, I like it. If it were a burden, I would definitely create a schedule and be more focused about it.
