Over the last three months, I've made on average slightly more than two transactions per week, most of which is due to buying food every 3 or 4 days. Everything else is a rounding error.
Now I won't claim my consumption pattern is typical, but it certainly shows that 0-1 transaction per day is possible. (What are the five shops you visit three times a week?)
Working from home during the pandemic, I’ve been making 4.3 transactions per week.
If I was still commuting, I’d add at least 5 a week for lunches, might add another 5 a week for train station Brötchen and cookie. If the restaurants were back to normal, might add two more per week for evening meals.
I think I prefer my new normal of the bulk shopping being a once a week collection, so that probably won’t go back to my old habit of whatever/wherever, but even then the local doesn’t have everything I want, so there will be a few additional transactions with grocery stores.
(My commute costs will likely be a once-per-year expense, so a rounding error for transactions per week).
