To avoid using plastic bags I used to carry my groceries or have them placed back in the wagon. That wasn't always practical, especially when I had more than a few items. These bags solved that problem. Their size, shape and durability make them perfect to use not just at Trader Joe's, but at any grocery of drugstore. I leave them in the car so even if I stop unexpectedly, I have them to use.
