I reused all my grocery store plastic bags for disposing of cat litter and other trash. When those bags went away I had to start buying new plastic bags for the first time.

That’s funny because when my locality switched from plastic to paper bags I was annoyed at having to buy trash bags for the bathroom for the first time but found the paper bags were excellent for litter cleanup since they stand up on their own and are easier to scoop into than a smaller fluttery plastic bag.
