For several years I have been using my small rectangular waste can with linings of grocery store plastic bags. This works quite well and is free. Then I started using a grocery curbside pickup service because of COVID-19. And for that, my store started using large heavy plastic bags. Since I no longer had access to the small plastic bags, I needed to find another source. I decided to buy the simplehuman bags that fit my can. Of course they fit perfectly, are high quality, and look great. Best of all, I was surprised how inexpensive they are. So I am happy and all set well into the future!
