What do you use to carry home the groceries? Paper? Plastic? Cloth? They each have their problems. Cloth is great if you're on foot, but when I'm driving and stocking up, I like plain old paper double bags the best. They support the food, travel well, and keep warm food warm and cold food cold. Trouble is, when you buy say, 5 bags of food, that's 10 paper bags - a lot of trees to sacrifice, right? Actually not, because doubled paper bags can be used over and over again. For months. And that's exactly what we do. And to make them easy to carry back and forth to the store, we keep them in a cloth shopping bag - a bag o'bags.
