FWIW, I have ADHD, and once I amassed like 30 of these things, I kept as many as possible stuffed inside one of them in my car. Then, I had like 30 opportunities between then and when I ran out to remember to bring all my bags to the car again. It worked out well. Now my grocery store has a give-a-bag, take-a-bag stand which is even better.
